Bright raw green salsa of tomatillo and serrano chile — Mexico's most popular table salsa.

About this recipe

Raw serrano salsa is the most popular table salsa in Mexico, present in virtually every taquería, café and home across the country. With fresh tomatillos, raw serrano chiles, garlic and cilantro, it is blended uncooked to produce a bright green, fresh salsa with the clean, direct heat that the serrano delivers without the bitterness of roasted jalapeño.

History & Origin

The serrano chile (Capsicum annuum var. serrano) takes its name from the sierras of Puebla and Hidalgo where it was originally cultivated, although today it is the most produced variety of fresh chile in Mexico after the jalapeño. With a Scoville rating of between 10,000 and 23,000 units, the serrano is noticeably hotter than the jalapeño but with a cleaner, less bitter flavour, making it the ideal ingredient for raw salsas where heat and freshness must predominate over complexity. The raw serrano and tomatillo salsa is one of the few Mexican preparations that is never cooked, as heat would destroy the freshness and bright green colour that characterise it. It is the sort of salsa an experienced cook can prepare in under five minutes and that transforms any taco, quesadilla or fried egg into something memorable. Its simplicity is precisely its genius: tart tomatillo, hot serrano, pungent garlic and herbaceous cilantro in perfect proportion.

Method

1
Remove the husks from the tomatillos and wash them thoroughly. Cut them into quarters. Remove the stalks from the serrano chiles.
💡 Use firm green tomatillos - overly ripe ones make the salsa excessively tart.
2
Place the tomatillos, serrano chiles (with seeds for more heat, without for less), garlic, fresh cilantro, white onion and salt in the blender.
💡 Start with 2 serrano chiles and add more if you prefer it hotter.
3
Blend on high speed for 30–40 seconds until you have a homogeneous salsa with some texture. Do not over-blend - the salsa should be green and fresh-looking, not foamy.
💡 If the blender does not start, add 2 tablespoons of cold water.
4
Taste and adjust salt. Serve immediately or refrigerate for up to 3 days (it will lose some of its green colour but retain the flavour).
💡 A squeeze of lime juice when serving brightens the colour and freshness.
