Green salsas: everything built on tomatillos

A tomatillo is not a green tomato

This is the most common confusion in the family. The tomatillo is its own plant, grown inside a papery husk, and it tastes nothing like a tomato: tart, citrusy, slightly astringent. In US stores it is usually sold loose near the jalapeños, with the husk still on.

That acidity is the whole point. A green salsa next to carnitas or fried fish does a job a tomato salsa cannot, because acid cuts through fat.

Same ingredients, different fire

Nearly every green salsa here starts from tomatillo, fresh chile and cilantro. What separates them is how the tomatillos meet heat.

Raw keeps all the acidity: sharp, fresh, best next to rich food, and short-lived.

Boiled trades some of that sharpness for sweetness and body. It is the salsa for chilaquiles and enchiladas, where it has to coat rather than cut.

Charred on a dry pan adds smoke and a faint bitterness from the blackened skins, which go into the blender. It is the thickest and most assertive of the three.

Crushed in a molcajete gives texture instead of a smooth purée, and tends to taste more of each individual ingredient.

Choosing the chile

Serrano is the default: thin, not very fleshy, with clean heat that does not change the salsa’s body. Jalapeño works but carries much more flesh, so you need more of them and the salsa comes out thicker and milder. For a sharper, hotter version, a few dried chiles de árbol change the character entirely — see the chile de árbol entry for how to handle them.

Rinse, time, and cilantro

Three habits fix most green salsa problems. Rinse the tomatillos until they stop feeling sticky. When boiling, stop as soon as they turn from bright green to dull olive; burst tomatillos leave their body in the water. And add cilantro last, pulsed briefly, because long blending turns it bitter and dulls the color.

If a salsa goes wrong anyway, the troubleshooting guide works by symptom.
