That simple blueprint - tomatillos, chiles, garlic - that you follow to make the previous salsa will lead you to another super salsa. The difference? You roast the garlic. That seemingly minor change takes barely any extra effort - after all, you're already roasting and toasting the other ingredients - but adds so much complexity and a haunting sweetness that plays off those tangy tomatillos. As for chiles, I love using smoky chipotles, but chiles de arbol add nuttiness and serious heat, while pasillas de Oaxaca, if you can get your hands on them, one-up chipotles with smokiness and a touch of fruitiness. The choice is yours.
