Chipotle peppers are smoked jalapeño chilies. These fiery, smoky chilies are sold dried in bags or canned in adobo sauce, a condiment made of chilies and spices. Many recipes call for just a spoonful or two of the sauce, but the remainder of the peppers and the sauce will keep in an airtight container in the refrigerator for up to two weeks. Or freeze them in an airtight container for up to two months. We’ve also mashed up the chipotles and added them to the sauce, but because the chilies are hotter than the already-hot sauce, use caution.
