Ingredients

1 tablespoon unsalted butter 

1 tablespoon extra-virgin olive oil, plus more for drizzling 

2 cloves garlic, thinly sliced (1 heaping tablespoon) 

1 pound shell-on jumbo shrimp (10 to 11 per pound), veins removed 

3 thyme sprigs 

Kosher salt and freshly ground pepper 

1/2 cup fino sherry 

18 littleneck clams, scrubbed 

Garlicky Beans, for serving

Frances’s Romesco Sauce, for serving

Fresh dandelion greens, for serving 

Preparation

Melt butter with oil in a large cast-iron skillet over medium heat. Add garlic and cook, stirring, until soft and translucent, about 1 minute. Add shrimp and thyme. Season with salt and pepper; cook until shells change color and start to peel away from shrimp, about 2 to 3 minutes per side. Transfer shrimp to a plate.

Add sherry to skillet; increase heat to medium-high. Bring to a boil and cook until reduced by half, 1 minute. Add clams. Cover with a lid or foil and cook until clams open, about 5 minutes. Discard any unopened clams. Return shrimp to skillet just to reheat. Serve, with beans and some of their broth, a drizzle of oil, pepper, romesco, and greens.
