Actually measuring ingredients is somewhat counter to the spirit of this recipe, but counting them is central. The eight components are:
ripe avocado
pressed or diced garlic
tomato salsa
lemon or lime juice
chili powder
plain yogurt
mayonnaise
salt
Smash 1 large avocado with 1/2 clove garlic. Add some (1/2 table spoon?--see what I mean?) mayo, similar amount of yogurt, and 2 tablespoons salsa. Squeeze in a bit of lemon juice and spice and salt to taste.
In general, I add everything, mix it up, taste it, and allow one round of adjustments. Serve with tortilla chips and 3 friends.
