- 2 Buying Mexican chiles in the US Which aisle to look in, the labeling errors that are everywhere, what to check before you pay, and which ingredients you genuinely cannot get.
- 3 Chile heat: the Scoville scale and how to control it What Scoville numbers actually mean, where the heat sits inside a chile, how to take it out, and what to do when a salsa comes out too hot.
- 4 How to fix a salsa that went wrong Bitter, watery, flat, too hot, separated or brown. What causes each one, what actually fixes it, and the two cases where nothing does.
Which one to read first
If you have a bag of dried chiles and no plan, start with working with dried chiles. Toasting, soaking, blending and straining are the same four steps for guajillo, ancho, pasilla, morita and every other dried chile, and once they are familiar most red salsa recipes stop needing their method explained.
If you are about to go shopping, read the buying guide first. US labeling of Mexican chiles is unreliable in a few very specific ways — fresh poblanos sold as pasilla, mulatos packed as ancho — and each one has a quick check you can do in the aisle.
If you are cooking for people with different tolerances, the heat guide explains where capsaicin actually sits in a chile, how to remove most of it without losing flavor, and why fat, sugar and temperature change how hot the same salsa feels.
If something already went wrong — bitter, watery, flat, too hot — the troubleshooting guide works by symptom, and says plainly which two problems have no fix.
