Chipotles are smoke-dried Jalapeno chiles, and are currently being sourced from Mexico. Almost one-fifth of the Mexican Jalapeno crop is produced to make the chipotle. Dried chiles should be whole and unbroken with deep color and a fresh scent. Chipotles should be stored below 70 degrees, in a low humidity environment in an airtight container. If properly stored, they can be used for six months or more. They rate a 7 on the Scoville heat unit scale. Chipotles have a wrinkled, dark brown skin and a smoky, sweet almost chocolaty flavor. They can be found dried, pickled and canned in adobo sauce. Chipotles are used most often in salsas, stews and other Southwestern dishes. They are rich in vitamin C, and low in calories.
