Start with sauce thickness, not just heat
Roast the tomatoes and tomatillos before blending. Roasting at about 400°F softens the vegetables, concentrates their juices, and gives the blender something richer than raw watery produce.
Chipotles in adobo are the heat engine, but heat alone does not fix thin sauce. Blend the roasted vegetables with sautéed onion and garlic, then simmer until the sauce darkens slightly and leaves a trail when you drag a spoon through the pan. That is the point where it is ready for chicken.
- 01Choose taut green tomatillos; wrinkled ones are past their prime.
- 02Roast tomatoes and tomatillos until softened and juicy, then add the pan juices to the blender.
- 03Start with fewer chipotles for a milder batch; add more only after tasting the simmered sauce.
