What is a good substitute for ancho chili powder?

One good substitute for ancho chili powder is guajillo chili powder. Guajillo chilies are slightly hotter than ancho chilies, but they still have a rich, fruity flavor that can enhance many dishes. If you don't have guajillo chili powder on hand, you can also try using pasilla chili powder, which has similar earthy and spicy notes as ancho chili powder. Other options include chipotle chili powder, which will add a smoky flavor to your dish, or paprika for a milder substitute. Ultimately, the best substitute will depend on the specific flavor profile you are looking to achieve in your recipe.
