This homemade chili powder is earthy, smoky, and complex. It will add bold flavor to chili, of course, but it's also great for seasoning roasted veggies, beans, soups, and more. See the post above for specific suggestions.
Use scissors to cut the stems off the guajillo or ancho chiles, then cut each chile in half and remove the seeds. Toast the chiles in a dry skillet over low heat with the cumin, coriander, and fennel seeds until fragrant, about 30 seconds.
Tear the chiles into small pieces and transfer them to a spice grinder. Add the cumin seeds, coriander seeds, fennel seeds, garlic, paprika, oregano, allspice, salt, and sugar. Grind into a powder, working in batches if necessary.
