Peel and pit the avocados, then grind them in the molcajete. Add the garlic, chiles and cilantro and keep grinding. Gently squeeze in the lime juice and add salt to taste. Transfer to a bowl and serve with fresh Mexican tortilla chips.
Chips
To make the tortilla chips, heat the oil in a large frying pan until it reaches 350 degrees F. Fry the tortilla wedges in batches, cooking each for about 3 minutes, or until they become a nice shade of golden brown. Sprinkle the chips with salt then keep them warm in a 200 degree F. oven.
