Long ago, I made some guacamole in a molcajete (a Mexican mortar and pestle made of lava stone), and now no one will let me make it any other way!!
In the molcajete, pound the following ingredients with a little salt into a rough paste. I add each ingredient in the following order, mashing each before adding the next.
1 small clove of garlic
4 serrano chiles, diced
¼ onion, diced
Some chopped cilantro
The end result looks like watery pesto. You can just as easily grind everything up in a blender—I still do, when no one is watching, with a pint jar and my 1950s Oster—but the texture is not the same.
A lot of people just finely chop all the ingredients, which is also very good—basically mashed-up avocados with pico de gallo. We’re in Mexico right now, and that’s what we get at the taquerías about half the time.
Add:
A little lime juice
3 very ripe avocados
Pound the avocados to break them up a bit, but not too much. The guacamole should be chunky.
You can put some diced tomato on top or fold it into the guacamole. Call me crazy, but I don’t like tomatoes with mine.
Diana Kennedy INSISTS on no garlic and no lime juice, but 1) all the Mexicans I know use both, and 2) I like it that way!!
