Shrimp recipes

Ingredients
1 pound large (16-20 count) raw shrimp, shelled* and de-veined, (if you want, keep the tail on for an attractive presentation)
2 tablespoons extra virgin olive oil
2-3 tablespoons butter
Salt
3-4 garlic cloves, slivered, or 1 Tbsp minced garlic
1/4 to 1/2 teaspoon red pepper flakes (less or more to taste)
2 tablespoons finely chopped parsley
Freshly ground black pepper to taste
1 tablespoon lemon juice 

Heat a sauté pan on high heat then reduce to medium high heat. Swirl the butter and olive oil into the pan. After the butter melts it will foam up a bit then subside. If using unsalted butter, sprinkle a little salt in the pan. Stir in the slivered garlic and red pepper flakes.
Turn shrimp over to cook on the other side: Stir the shrimp and arrange them so that you turn them over to cook on the other side. Continue to cook on high heat for another minute.
Remove the pan from the heat. Sprinkle the shrimp with parsley, lemon juice, and black pepper, and toss to combine.
Serve as is, or with crusty bread, over pasta, or over rice (for gluten-free version).

Ingredients
1 pound medium-small shrimp, peeled and deveined
3/4 cup lime juice (juice from 4-6 limes)
3/4 cup lemon juice (juice from 2-3 lemons)
1 cup finely chopped red onion
1 serrano chile, ribs and seeds removed, minced
1 cup chopped cilantro
1 cucumber, peeled diced into 1/2-inch pieces
1 avocado, peeled, seed removed, cut into 1/2-inch chunks

1 Boil the shrimp: In a large pot, bring to a boil 2 quarts of water, salted with 1 tablespoons salt. Add the shrimp and cook for 1 minute to 2 minutes max, depending on size of shrimp. (Over-cooking the shrimp will turn it rubbery.) Remove shrimp with a slotted spoon and place into a bowl of ice water to stop the cooking. 2 Drain the shrimp. Cut each piece of shrimp in half, or into inch-long pieces. Place the shrimp in a glass or ceramic bowl. Mix in the lime and lemon juice. Cover and refrigerate for a half hour.
3 Mix in the chopped red onion and serrano chile. Refrigerate an additional half hour. 
4 Right before serving, add the cilantro, cucumber, and avocado.
