In a large pot of salted, boiling water cook shrimp until bright orange - approximately two minutes. Drain. When cool enough to handle, remove shells and set aside. In a glass or metal bowl whisk garlic, lemon juice, oil, parsley, thyme and lemon peel together. Season to taste with salt and pepper. Add shrimp and toss to coat. Refrigreate for several hours, tossing
occasionally. Serves 6
