Chipotle chiles: Chipotle chiles in adobo sauce are smoked jalapeños packed in a flavorful sauce. Look for the small cans with the Mexican foods in large supermarkets. Once opened, they’ll keep up to 2 weeks in the refrigerator or 6 months in the freezer. You can also find them dried with other chiles or at melissas.com and ground in the spice section of many supermarkets.
