Southern California’s blessed with locally grown fruit throughout the year. Citrus is king during these cooler months. Even a mid-sized farmers market like the one at UC Irvine boasts many vendors selling different varieties of lemons (sweet Persian; extremely tart Lisbon; mild aromatic Meyers), oranges (pink and juicy Cara Cara; tart, sanguine blood oranges, several kinds of mandarins; the ever popular navel), and grapefruit scions.

Last weekend, I spied Cal Poly Pomona’s ag school selling a hybrid called a frua, an heirloom love child of a grapefruit and a mandarin orange. It’s the size and shape of the former, its skin color somewhere between the two. Its flesh tempers the tartness of a grapfruit with the juicy, not oversweet flavor of a mandarin.

Most interestingly, the frua’s thin skin is tender and edible, with a mild and pleasant bitterness that might make a terrific marmalade. I bought four of these mongrel fruit with that intent. If you happen to have Grandma Tildy’s killer marmalade recipe in your clutches, help a brother out and post it, willya?

The UC Irvine farmer’s market is held every Saturday morning in the shopping center parking lot at Campus and Bridge. While there’s a wide variety of vegetables and fruit for sale, right now, citrus rules the roost for flavor, variety, and low prices.
