Ingredients
2 tablespoons finely chopped white onion
1 tablespoon minced fresh serrano or jalapeno chile, including seeds, or more to taste
1/2 teaspoon kosher salt, or 1/4 teaspoon fine salt (or to taste)
1/4 cup chopped cilantro, divided
1 large or 2 small ripe Mexican Hass avocados, halved and pitted
Instructions
  1. Mash the onion, chile, salt (the coarseness of kosher salt helps you make the paste), and half of the cilantro to a paste in a molcajete or other mortar. You can also mince and mash the ingredients together on a cutting board with a large knife or a fork, and then transfer the paste to a bowl.
  2. Score the flesh in the avocado halves in a crosshatch pattern (not through the skin) with a knife and then scoop it with a spoon into the mortar or bowl. Toss well (it should be like salad properly dressed in vinaigrette), then add the rest of the cilantro and mash very coarsely with a pestle or a fork. Season to taste with lime juice (if you'd like) and additional chile and salt.
