Chipotle published their Guac recipe several years ago.. Its not a big secret.
2 ripe Hass avocados (In the restaurant, we use 48 per batch, multiple times per day)
2 teaspoon lime juice
2 tablespoon cilantro (chopped)
¼ cup red onion (finely chopped)
½ jalapeño, including seeds (finely chopped)
¼ teaspoon kosher salt
Don’t forget the tomato.
