Food writer Michael Ruhlman has thrown down the gauntlet on his blog, where he's challenging readers to make a BLT from scratch. Don't worry, you don't have to raise the pig:
From scratch means you grow your tomato, you grow your lettuce, you cure your own bacon or pancetta, you bake your own bread (wild yeast preferred and gets higher marks but is not required), you make your own mayo. All other embellishments, creative interpretations of the BLT welcome.
This sounds like a great idea. I think we're going to have to buy one of those upside-down tomato buckets and try growing some plants in the SE office window.
