4 clusters of rock crab
1/4 cup olive oil
1 lb peeled and deveined large shrimp (raw; 20 to 25 per lb)
4 large garlic cloves, left unpeeled and forced through a garlic press
1/2 teaspoon dried hot red-pepper flakes
1/2 cup dry white wine
1 teaspoon salt
1/2 teaspoon black pepper
5 tablespoons unsalted butter
3/4 lb Gemelli pasta
1/2 cup chopped fresh flat-leaf parsley
Bring a 6- to 8-quart pot of salted water to a boil.
Meanwhile, heat oil in a 12-inch heavy skillet over moderately high heat until hot but not smoking, then sauté shrimp, turning over once, until just cooked through, about 2 minutes, and transfer with a slotted spoon to a large bowl. Add garlic to oil remaining in skillet along with red pepper flakes, wine, salt, and pepper and cook over high heat, stirring occasionally, 1 minute. Add butter to skillet, stirring until melted, and add crab and simmer for 10 minutes flipping the crab once then remove clusters and stir in shrimp. Remove skillet from heat.
Cook pasta in boiling water until just tender, about 3 minutes. Reserve 1 cup pasta-cooking water, then drain pasta in a colander. Toss pasta well with shrimp mixture and parsley in large bowl, adding some of reserved cooking water if necessary to keep moist. Serve immediately with crab cluster. Bon Appetit!
