Chipotle-Shrimp Tacos With Fennel and Beans

1. With the side of a heavy knife, mash 1 tablespoon garlic and 1/2 teaspoon salt to a paste. Transfer to a bowl; stir in chipotles and sauce and 1 tablespoon olive oil. Add shrimp and toss to coat. Let stand at least 15 minutes (or refrigerate in an airtight container up to 1 day).

2. Heat remaining 2 tablespoons olive oil in a skillet over medium. Add remaining 1 tablespoon garlic and cilantro stems; cook until fragrant and garlic is just golden, about 1 minute. Stir in beans and 1/2 cup water. Season with salt and pepper. Reduce heat and simmer, mashing some beans with the back of a spoon, until liquid has mostly evaporated, 3 to 5 minutes. Season to taste and squeeze half of lime over top. Remove from heat; cover to keep warm.

3. Heat grill to high. Thread shrimp onto metal or presoaked wooden skewers (2 to 3 a skewer). Brush grates with vegetable oil. Grill shrimp, undisturbed, until charred in spots and easily lifted from grates, about 2 minutes. Using tongs, flip skewers and cook until shrimp are opaque, about 1 minute more. Transfer to a plate; tent with foil.

4. Blister tortillas over direct heat, flipping once, about 30 seconds each. Wrap in a clean towel to keep warm. Just before serving, toss fennel with juice of remaining lime half and a generous drizzle of olive oil; season with salt and pepper. To serve, pile tortillas with beans, fennel slaw, and a shrimp skewer. Top with cilantro leaves and sour cream.

Cook's Notes

If marinating the shrimp overnight, thread them, then drizzle with olive oil just before grilling.
