"There's not that much difference between sour cream and an avocado, which is really a big ball of fat that grows on a tree," says Alton Brown. Avocado is not an ingredient so much as a carrier for the main players – the tomato and the onion – and the seasoning: lime, chili powder, and garlic powder. Brown pits and peels the avocado on a cutting board, then spritzes it with lime juice from a spray bottle; this will keep the fruit from browning. He then mashes with a potato masher and folds in ingredients with an oversize sheetrock knife he found at a hardware store. This is because he is a little crazy.
