Salsa de aguacate

Add the juice of at least one lime to the avocado; it oxidises quickly and needs a fair amount of acid.

Add the rough chopped cilantro, the roasted and raw serrano, one clove of garlic and a squidge of salt.

Add a quarter cup of water, starting with half of it, and blend, scraping the sides so no big chunks remain.

Thin further with a little splash of tequila and more water as needed.

If keeping it, cover with plastic wrap pressed down onto the surface; do not make it more than several hours ahead.
