Clean your shrimp, peeling off shell and deveining. You can leave the tails intact for presentation if desired. In a medium-sized pan, sauté olive oil, butter, and garlic for about 1 minute. Add shallots and shrimp and sauté for another 2 minutes on each side of shrimp. Flame with brandy. Add sherry and sauté for about 2 more minutes. Serve shrimp scampi over rice or your favorite pasta.
