I live in Austin. I have loquats in my yard, and every spring I gather dewberries if I can, and agarita berries (sort of a holly bush, they're sharp tasting and make a great jam with a really complex flavor, great with Valentina hot sauce over pork or chicken or eggs), the two local types of grapes (mustang and fox), and sometimes the mustard greens. I haven't found anything really good to do with the mulberries (could they be used to reinforce dewberry cobbler?). I got a bunch of prickly pear tunas a few weeks ago...they looked so good, but there's very little flesh, mostly seeds. Might make a good sorbet or something like that. Also my back yard had a truckload of chilpectines last year, I don't know how well they'll do this year.
