RECIPE: Homemade Guacamole

Cut the avocado in half length-wise, rotating your knife around the pits. Separate the halves and remove the pits. With a big spoon, scoop out the flesh and put it into a bowl. Discard the peel. Add the onion, serrano or jalapeno pepper, cilantro, and lime juice, and mash together with a fork, a potato masher, or your very clean hands. Gently fold in the tomato, and season with salt and pepper to taste.
