I live in San Francisco, so let's be honest: it's not like I just survived through a long, hard winter. Not as long and hard as some of you have. Through the shortest days, we still have lettuces and citrus, year-round markets, and quite a variety of fruits and vegetables. But even the heartiest locavores among us get a little weary of butternut squash and stored apples and canned tomatoes. Enter Spring.
