A discussion about how to make guacamole usually ends in tears. Everyone knows how it should be made, but no one can agree on just how. It depends on what you like. And while I like garlic, I don't like it in guacamole, where it tends to turn bitter after a while. I use a lot of spring onions (scallions), a lot of lemon or lime juice, and then all bets are off. I love cilantro, so in that goes - usually last, a lot of black pepper, and more or less fresh or dried chile.
This is a recipe for two people with leftovers. Four as a snack before dinner.
