Chipotles are dried smoked jalapenos. They are sold most commonly canned in adobo sauce. As you know, they are also available dry.
I use them in a cuban black bean soup recipe, chili, etc. You can add them to most Southwestern/Mexican recipes. You can also grind them up and use them in recipes. They also add a great flavor to BBQ sauces and salsas (rehydrated).
