‘Super Carbolicious’ 4-H Food Fiesta challenges young chefs
Inside a quiet classroom, Sadie, a 4-H member in Orange County, stands in front of two judges with an insulated cooler bag in hand. From it she pulls out plates, utensils and napkins and sets them down on the table. She unzips the bottom compartment and carefully reaches for a cast iron platter with golden fluffy pancakes piled on top.
“Would you like syrup with your pancakes? I highly recommend it,” said Sadie, an eighth grader who is participating in the annual 4-H Food Fiesta for a second time.
4-H, a youth development program supported by the University of California Agriculture and Natural Resources and administered through local UC Cooperative Extension offices, promotes hands-on experiential learning for all youth.
Rita Jakel, 4-H program coordinator for Orange County, described the Food Fiesta event – intended for ages 5 to 18 – as an opportunity to practice and showcase public speaking skills through a fun, food-related competition.
Youth present their creations before a panel of evaluators, who ask them to describe how they prepared the dish and why, and how they managed challenges throughout the process. The interaction between youth and adult leaders provides a unique opportunity for youth to practice career readiness skills such as job interviews and public speaking.
This year's theme was “Super Carbolicious” and 4-H participants were encouraged to make their favorite dishes using ingredients like pasta, potatoes and bread. Carbohydrates are often perceived as unhealthy, which is not a helpful mindset to have when teaching youth about nutrition. Carbohydrates provide the body with glucose, which is converted into energy that people need to function throughout the day.
Some of the dishes that were presented during the Food Fiesta included chocolate chip banana bread, cheesy baked potatoes, cookies and Nutella-stuffed crepes. 4-H member Kaitlin had only ever attended the Food Fiesta to cheer on a friend. This year, she decided to participate and presented pumpkin macaroni and cheese as her entry.
“Pumpkin mac and cheese is better than the regular one because there's a lot more flavor and you have to use two cheeses: cheddar and parmesan,” explained Kaitlin, a seventh grader. When asked what motivated her to participate instead of a being a bystander this time around, Kaitlin said that she wanted to work on her presentation skills.
“Usually, I'm a bit shy and I don't like to share that much. The Food Fiesta helped me practice speaking up more so that I can accomplish my goals,” Kaitlin said.
Sadie, who loves public speaking, admits that it wasn't always a strength of hers. “There was a time when I hated public speaking. But when I joined 4-H's cake decorating, poultry and food fiesta events, I got more comfortable with public speaking,” she said. “Now, I like going to events and showing off. I get to show off turkeys, my cakes and, today, I presented homemade pancakes.”
Helping to keep the day's festivities running smoothly were two 4-H state ambassadors: Michaela and Laurelyn, two high school seniors. Both have been involved in 4-H for over nine years, with Laurelyn being a third-generation 4-H member. “My grandmother grew up in a 4-H club in Orange County. She still raises breeding lambs for 4-H members to this day,” said Laurelyn, whose mother was a 4-H member in San Joaquin County.
As state ambassadors, they are responsible for creating and presenting workshops during state, national and regional events. “We also engage the public via social media, specifically TikTok and Instagram (@4horangeco),” said Michaela, who is in her second year as an ambassador.
During the Food Fiesta, Michaela and Laurelyn made themselves available to answer questions from participants and their families. Both ambassadors agreed that seeing parents involved in 4-H should not come as a surprise. “Being in 4-H is a family effort. This isn't an extra-curricular where you just drop your kids off and leave,” said Michaela.
Laurelyn shared that the biggest misconception others have about 4-H is that they think it's about introducing youth to agriculture or livestock. There's a civic engagement and leadership component to it, too. “If parents knew about all the ways 4-H can benefit their kids, I think more people would want to join us,” she said. “And they're finding fun ways to help us learn life skills, like this Food Fiesta.”
The homemade dishes weren't the only thing to look forward to, however. In another building, Sandy Jacobs, volunteer event coordinator, and her team set up a kitchen quiz for members. On several tables, there were different cooking tools and participants were challenged to name as many tools as they could.
In another classroom, while some members were presenting food, others presented their themed table setting décor. Participants had to prepare a complete table setting entry including a menu card, centerpiece and table settings for two. Judges considered creativity, use of color, table setting etiquette, knowledge in talking to the judges, and appearance in their evaluation.
Finally, to wrap up the day, members competed in a cupcake decorating competition. Participants were responsible for bringing their own supplies including tools and edible decorations for Cupcake Wars. Depending on their age group, participants had 20 minutes to decorate two to four cupcakes, each of a different theme.

New avocado proves tasty, safer to harvest at UC ANR Research and Extension Centers
A new avocado, one that complements the widely known ‘Hass,' will hit the world market soon. The ‘Luna UCR' variety (trademarked and patent pending) has several characteristics that should be of interest to both growers and consumers, said Mary Lu Arpaia, University of California Cooperative Extension subtropical horticulture specialist based at UC Riverside.
From the grower perspective, the tree is about half the size of the leading variety while producing approximately the same yield per tree as ‘Hass,' meaning that growers could plant more trees per acre, therefore increasing yield. It also makes harvesting easier and safer.
Another advantage is the flowering behavior of the tree. Avocado trees are categorized into either Type A or Type B flower types. It is generally accepted that you need both flower types in a planting to maximize productivity. The ‘Hass' is an “A” flower type and ‘Luna UCR' is a Type “B.”
This is a potential boost for growers since the current varieties that are “B” flower types ripen green and generally receive lower prices for the grower. Similar to ‘Hass,' however, the ‘Luna UCR' colors as it ripens.
“Hopefully, it will receive similar returns to the ‘Hass' once it is an established variety,” Arpaia added.
Fruit breeding is a long-term process that she has navigated by building upon the work of her predecessors. Of course, Arpaia has had strong support from colleagues as well, including Eric Focht, a UC Riverside staff researcher and co-inventor of ‘Luna UCR.'
“We had been looking at ‘Luna UCR' for some time and it was always a very good eating fruit,” Focht said. “After the 2003 release of ‘GEM' (registered and patented as ‘3-29-5', 2003) and ‘Harvest' (patented as ‘N4(-)5', 2003) varieties, ‘Luna UCR' was always the top contender for a next release due to the small, narrow growth habit, “B” flower type and the fruit quality.”
“It's a very nice-looking fruit as well and seemed to be a pretty consistent bearer from year to year.”
A glimpse at how it all started
In spring 1996, Arpaia took over the UC Avocado Breeding Program following Guy Witney who led the program from 1992 to 1995, and Bob Bergh whose initial efforts in the 1950s were foundational in the inception of ‘Luna UCR.'
Arpaia recalls the first trials in the early 2000s of ‘Luna UCR,' which were tested alongside other promising selections from the Bergh program. “There were a lot of varieties that didn't perform well, some of which had poor storage life, an important trait that we need if we are going to get the fruit to consumers across the country,” said Arpaia.
The original seed and selection were planted at the Bob Lamb Ranch in Camarillo, and originally advanced trials of the ‘Luna UCR' variety were planted in four locations: UC Lindcove Research and Extension Center in Tulare County, UC South Coast Research and Extension Center in Orange County, a privately owned farm in San Diego County and another one in Ventura County.
The RECs are among the nine hubs operated by UC Agriculture and Natural Resources to support research and educate the public on regional agricultural and natural resource challenges.
ANR Research and Extension Centers become vital
Unfortunately, the 2017 Thomas Fire burned the avocado trees in Ventura, said Arpaia. After a change in management, the trial located in San Diego County was also terminated, leaving the two trials at Lindcove and South Coast REC.
“South Coast REC has a long history of supporting research and extension activities of high value crops important to California, including avocados,” said Darren Haver, director of the South Coast REC, which was often used to show growers the new varieties that were being developed.
“Many of the REC staff have worked with the avocado-breeding program researchers for more than two decades and continue to work closely with them to ensure the success of new avocado varieties, including ‘Luna UCR',” he added.
In addition to the support provided by South Coast and Lindcove RECs, Arpaia said that UC Kearney Agricultural Research and Extension Center in Fresno County – another UC ANR facility – made it possible for her team to conduct critical postharvest and sensory research, and consumer testing of the fruit, which included up to six-week trials of fruit ratings for storage life and taste.
“UC ANR has played an important role in our ability to not only identify ‘Luna UCR', but in preparing it for the world market, too,” she said.
Preparing to share with the world
Since 2015, Focht had been collecting data for the patent application. Now that he and Arpaia have successfully patented and trademarked ‘Luna UCR,' they are preparing to expand production by engaging interested growers with the commercial partner, Green Motion who is based in Spain.
“Green Motion contracted for 1,000 trees to be generated by Brokaw Nursery and those trees are currently being distributed, with earliest field plantings likely taking place in fall,” explained Focht.
Focht also said that Mission Produce, based in Oxnard, CA has contracted to graft over a small number of “B” flower type pollinizer trees to the new ‘Luna UCR' variety, possibly making way for a small number of avocados to be available the following year.
Once planted, the avocado trees will come into “full” production in about five years.

More than a TikTok trend, preservation is the future of food
UC Master Food Preservers give live canning demonstrations at Orange County Fair
If you visited the Orange County Fair in Costa Mesa during the past month, you might have seen the Master Food Preservers of Orange County in their rustic farmhouse-themed kitchen located in the OC Promenade exhibit hall.
If the decor did not catch your eye, the colorful rows of glass jars lined along the walls certainly would have. For an entire month, three volunteers conducted live canning demonstrations from 11 a.m. to 8 p.m. five days a week. They are with the UC Master Food Preserver Program, a public service and outreach program under UC Agriculture and Natural Resources.
The OC Fair is UC Master Food Preserver's largest event in Orange County. Last year, the UC Master Food Preservers engaged 7,000 people at their booth.
Food preservation has a deep history rooted in human survival. Whether freezing, drying, fermenting or pickling, preservation is a practice that has prolonged the life of food and humans. Other benefits include reducing food waste and increasing food security.
The latest form of preservation, called canning, was introduced in the early 1800s according to a Smithsonian article. By placing food in a glass jar and heating it to a certain temperature for a prescribed period of time, oxygen is removed and a vacuum is created. This process prevents the growth of undesirable bacteria, yeasts and molds, thus keeping the food from spoiling.
This is what you would have found the UC Master Food Preservers demonstrating at the OC Fair.
During her shift, Flo Vallejo, UC Master Food Preserver since 2018, carefully chopped carrots and daikon into thin slices and placed them inside small mason jars with spices inspired by Vietnamese cuisine.
Between the produce donated by Melissa's Produce and the diverse spices donated by Tampico Spice, the possibilities of what you will see the UC Master Food Preservers canning are endless.
“This is something my great-grandmother, grandmother and mother did. I never understood it because they didn't let the little kids in the kitchen,” said first-year UC Master Food Preserver Alice Houseworth.
Many of the UC Master Food Preservers have some experience with canning, whether it be a practice passed down from generation to generation, or, in Houseworth's case, something they watched their elders do as a child.
Some might view canning as a hobby, but according to the UC Master Food Preservers, food preservation is an opportunity to prepare for economic and climatic change. 
Esa Kiefer, another UC Master Food Preserver since 2018, expressed her concern for the rising prices of food and decline in arable land. “I feel like now is the time to prepare for these changing times,” she said. “Who knows what the future will look like for food?”
Perhaps the future of food will come from glass jars.
“You can even can chicken,” Houseworth said. “When it's cheap at the grocery store, you can buy it and use the pressure canner and then eat it when chicken prices go up.”
Vallejo recalls when pickling and canning were trending on social media during the stay-at-home phase of the COVID-19 pandemic, making it difficult to find mason jars.
“Preservation has been done for a long time. When I saw a lot of people doing it during the pandemic, I thought it was just because people had time on their hands. But I realized that many became concerned about the food supply and accessibility,” she explained.
The resurgence in food preservation interest makes the work of the UC Master Food Preserver program much more essential. Whether you are feeding a large family, living in a food desert or managing a tight budget, food preservation ensures you are fed today, tomorrow and beyond.

You, too, can grow California’s oldest living orange variety
Sweet Mother Orange Tree released from quarantine
The 1000th tree okayed for growing by California's Citrus Clonal Protection Program happens to be the oldest living orange variety in the state.
The program, housed at UC Riverside, is the first of its kind in the world. It began in the 1950s, and its scientists spend up to three years testing and clearing citrus trees of disease so they can be released to commercial and private growers.
By law, every citrus tree newly propagated in California can be traced back to one mother tree created at UCR through the protection program. Program Director Georgios Vidalakis and his group begin their process by testing incoming trees for more than 30 citrus diseases, whether the diseases are known to have emerged in the state or not.
The treatment for any disease identified in that first round of testing is to make a new mini tree from a few cells of the original budwood — short, leafless twigs with buds meant for propagation. “We use special plant cells for this process that diseases cannot penetrate,” Vidalakis said.
After the mini tree grows large enough, program scientists go back and do a second round of testing for disease, making sure they picked the right cells for propagation and eliminating any prior trace of illness.
If it passes the arduous second set of tests, the new tree gets a variety index or VI number that accompanies it for the rest of its life, and it is released to the public.
Dubbed the Mother Orange Tree, Bidwell's Bar is a sweet Mediterranean orange brought to California from Mazatlán, Mexico, and planted in 1856. It was first planted near the Bidwell Bar Bridge near Oroville, then dug up and replanted twice.
Its survival skills are some of the reasons Tom Delfino, former California Citrus Nursery Society director, recommended the old orange tree for the protection program.
“Apparently this variety is very rugged,” Delfino said. “Not only has it survived a lot of cold Northern California winters, but the tree has been dug up and replanted twice — once to protect it from impending flood, and again to make way for the Oroville Dam.”
Much of the state's orange industry is based in areas with warm weather. Delfino, who lives in the San Francisco Bay Area, finds citrus an exciting challenge to grow. By suggesting Bidwell's Bar for approval, he was hoping the protection program would clear it so he could buy its budwood.
On the occasions he has visited the original tree, Delfino said the fruit in reaching distance was always gone. “I think it must be tasty because locals grab it for themselves,” he said. “Makes me even more eager to grow and eat my own. I'm extremely pleased the VI testing is completed so I can acquire it.”
Delfino also hopes that this variety will catch on with commercial growers.
“My thought is our citrus industry is concentrated in the southeastern San Joaquin Valley and is subject to a number of pests that like the warm climate there,” Delfino said. “Though this has seeds, which may be a deterrent, it can be grown in colder areas that discourage some of those insects.”
The tree arrived in California nearly two decades before the better-known Washington Navel orange grown by Eliza Tibbets in Riverside. The navel is named for a structure at the bottom end of the fruit, which resembles a belly button. This structure is actually a separate fruit inside the larger fruit. The Washington Navel is also seedless, contributing to its popularity.
“Bidwell's Bar is an example of what was grown in California before the Washington Navel came to dominate, and now that it has a VI number, others can grow it too,” said Tracy Kahn, curator of the Givaudan Citrus Variety Collection at UCR.
Kahn says it's important to preserve the genetic material from a tree with such significance to California. “Some people were worried it was going to die, but now we have an officially cleared source of this historic tree, and it is protected for future generations,” Kahn said.
