Chipotle chiles in adobo are smoked and dried jalapeños in a tomato-based puree. They are widely available and sold in a can; generally, you can find them in the international aisle of a grocery store. The can comes with more chiles than what you need for a single recipe; use your extra for any of these recipes with chipotle chile peppers. (Two of my top favorite recipes that use chipotle chiles are Instant Pot Chicken Mole and Instant Pot Shredded Chicken Tacos.)
