The name is deceptive: This is a shop with regular hours, not a weekend event. For cooks who despair of finding exotica like in-season cherries for less than $7 a pound, or for those who have heard tell of mythical eggplants that come in colors other than purple but have never actually witnessed such sights, the Guadalupe market is a mecca. It's not a tiresome gourmet shop with the precious-gem prices we've come to expect for things that should be everyday items, like ripe tomatoes or local grapefruit. This is a straightforward produce market, run by people who understand that they're selling vegetables, for goodness sake, not Russian caviar. Guadalupe Farmer's Market's plentiful produce is fairly priced, always fresh, and local whenever possible. Better yet, its fruits and vegetables taste like foodstuffs you've only heard about from elderly relatives who swear no one sells produce like they did "way back when." Guadalupe does.
