Mexico. Salsa verde is pre-Columbian — tomatillos (tomate verde) are native to Mexico and were cultivated by the Aztecs. The tomatillo appears in Aztec market records and in 16th-century Spanish chronicles of New World foods.
Mexican salsa verde (green sauce) is roasted or boiled tomatillos, serrano or jalapeño, garlic, white onion, and coriander — blended to a sauce with a bright, acidic, herbal character. It is one of the two foundational salsas of Mexican cooking (salsa roja is the other). It should be tart from the tomatillo, herbaceous from the coriander, and have moderate heat from the chilli. It is both a table salsa and a cooking sauce.
Applied to tacos, enchiladas, huevos rancheros, or served as a dipping salsa alongside tortilla chips. Salsa verde is a utility ingredient — it appears throughout Mexican cooking rather than in one specific application.
{"Tomatillos: the husked, sticky green fruit is the base. For roasted salsa verde (richer, smokier): char under a broiler or on a comal until blistered and slightly blackened. For boiled (brighter, more acidic): simmer in water until just soft","Serrano chilli: more heat and a brighter flavour than jalapeño — the standard choice for salsa verde. Remove seeds for mild, keep for hot","Garlic: 2 cloves roasted with the tomatillos — raw garlic produces a sharp, harsh note in a fresh salsa","The blend: tomatillos, chilli, garlic, and onion first — blend until almost smooth. Add coriander at the end (it oxidises quickly) and pulse briefly","Season: salt and a small amount of lime juice. Taste — the salsa should be bright, tart, and herbal","Rest: 30 minutes at room temperature before serving — the flavours integrate and mellow"}
The moment where salsa verde lives or dies is the tomatillo roasting — the tomatillos must be charred, not just softened. The char on the skin, when blended in, adds a smoky, bitter note that balances the tartness of the fruit. Under-roasted tomatillos produce a one-dimensional, aggressively tart salsa. A well-roasted tomatillo has black patches, a soft interior, and a complex sweet-sour-smoky flavour.
{"Using raw tomatillos: they are bitter and astringent uncooked — some form of heat (roasting or boiling) is required","Over-blending: a smooth, uniform salsa lacks the texture of a properly made version — some coarseness is correct","Adding too much coriander: it should be a note, not the dominant flavour"}
