Chipotle chiles are smoked jalapeños. You can usually find them in small cans in the Mexican or Latino foods aisle of your supermarket, and they tend to be “en adobo,” which means packed in a sauce of vinegar, tomato sauce, and spices. We love chipotles because they’re smoky and spicy and rich-tasting. But if you can’t find them, or you have everything else for this recipe but that, you can leave them out. Use 1⁄2 teaspoon smoked paprika or 1 teaspoon smoky hot sauce if you’ve got that, or something else spicy that you like — or skip the spice altogether.
