The smoked red jalapeño, known as the chipotle chile, has gained such popularity that there's even a couple of cookbooks devoted to it! It particularly works well with barbecuing and grilling, both of which have considerable smoke associated with them.
Here's a pickled chile recipe from Tlaxcala. These sweet-hot pickled chiles can be the basis of a sauce of their own if they're further puréed, or they can be served as a condiment with enchiladas and other main dishes.
Note that this recipe requires advance preparation.
Gorgeous insists that his sauce is secret, but if he wanted to keep it that way, he should never have told me the ingredients. We experimented in Dave’s and Mary Jane’s kitchen until we got the sauce right. It can also be used on chicken. It is a grill sauce, designed to be brushed on during the grilling process, but it has a lot of sugar in it, so take care that it does not burn. The sauce yield is about 1 cup.
