Chipotle chile in adobo sauce comes in a can and consists of plumped smoky flavored chipotle chile (which is smoked and dried jalapeño) in a rich sauce made with dried ancho chile peppers, garlic, and vinegar. In the U.S., you'll find it in cans in most grocery stores and Latin American markets. In Europe, it's slightly harder to happen upon. As a substitute, the authors suggest a few crushed chili flakes combined with a little smoked paprika.
