Ingredients

Fine sea salt, for purging clams 

4 pounds littleneck clams (about 40), scrubbed 

1 1/2 cups fregola (available at gourmet markets) or pearled couscous 

Kosher salt and freshly ground pepper 

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

2 tablespoons unsalted butter 

4 cloves garlic, thinly sliced (1 tablespoon) 

1 Fresno chile, thinly sliced (2 tablespoons) 

1 cup dry white wine, such as Sauvignon Blanc 

4 links andouille sausage (12 ounces), cut into 1 1/2-inch pieces 

3 ears corn, shucked and cut into 1 1/2-inch rounds 

1/2 cup packed cilantro leaves, roughly chopped 

Lime wedges and hot sauce, for serving 

Preparation

In a large bowl, stir 2 tablespoons sea salt into 8 cups cool water. Add clams; let stand 30 minutes, then drain and rinse. Meanwhile, cook fregola in a large pot of salted boiling water until al dente, 8 to 10 minutes. Drain; drizzle with oil. Wipe out pot.

In same pot, heat 1 tablespoon each oil and butter over medium-high. Add garlic and chile; cook, stirring, until fragrant, 1 to 2 minutes. Stir in wine, 1/2 cup water, clams, sausage, and corn. Bring to a boil, then reduce heat to medium, cover, and cook, stirring occasionally, 12 to 16 minutes, transferring clams as they open to a covered bowl. Transfer corn and sausage to bowl once all clams are open. Stir remaining 1 tablespoon butter into broth; keep warm.

Spoon fregola onto a platter and drizzle with half of warm broth; scatter some cilantro over. Top with clam mixture, then pour remaining broth over. Top with remaining cilantro, and serve with lime wedges and hot sauce.
