I used to buy chipotle peppers in adobo sauce, thinking that they met all of my ingredient requirements-oil free vegan, whole food. Lesson learned – always read the label. The store bought version has oil in it. So off I go to make my own. In my version I purée all of the peppers and use about 3 tablespoons for every chile called for in a recipe.
*Taste the soaking liquid. If it is bitter, discard it and use water instead.
