I don't want to write a brief description, but I hope this is long enough.
When should the lime juice actually touch the fruit to prevent rapid oxidation? Historically rooted in Mesoamerican cuisine, traditional preparation relies on a molcajete to break down aromatics into a cohesive paste before the fat of the avocado is introduced. Crushing garlic and serrano or jalapeño peppers with coarse salt creates a uniform slurry, distributing capsaicin evenly throughout the mixture rather than leaving sharp pockets of heat. Tomatoes, when added, should be seeded to prevent excess water from breaking the emulsion.
Over-processing turns avocados from a creamy suspension into an undesirable baby-food consistency. Use a wide fork or a potato masher, leaving some half-inch chunks intact to maintain structural integrity.
