People are always fucking up guac. Namely, by adding stuff like onions or salsa. Excuse me, but if I want to taint my avacado with salsa I can do the mixing myself. In my opinion, avacados are a form of edible gold and should be messed with as little as possible (the lemon in this recipe will keep the avacado from going that icky black / brown).
3 large perfectly ripe avacados
5 garlic cloves, minced
3 tablespoons fresh lemon juice
Mash the avacados. Mix everything else. Gorge yourself.
