These shrimp tacos get a spicy boost from a marinade that includes chipotle pepper in adobo sauce.

Chipotle peppers are jalapeño peppers that are smoked, which intensifies their flavor. Look for canned chipotle peppers in adobo sauce in the ethnic aisle of most grocery stores. This recipe calls for one pepper with some of the sauce, so you don’t use the whole can. But you can freeze what’s left. To freeze the peppers, place individual portion sizes on a plate and put the plate in the freezer. Once frozen, work the clumps of peppers and sauce off the plate and into a freezer bag. They’ll keep for a year in the freezer.

The shrimp is tasty just with the slaw, which has a slight spiciness to it. But we’ve included some favorite garnishes such as cilantro and avocado that make for an interesting and pretty taco.
