1 pound pasta
4 tablespoons butter
4 tablespoons extra virgin olive oil
1 large shallot (or 1/4 cup finely diced onion), finely diced
5 cloves garlic, chopped
pinch of red pepper flakes, optional
20 large shrimp, about 1 pound, peeled and deveined
salt and pepper
1/2 cup dry white wine
1 lemon, juiced
1/4 cup finely chopped parsley leaves

For the pasta, put a large pot of water on the stove to boil. When it has come to the boil, add a couple of tablespoons of salt and the pasta. Stir to make sure the pasta separates; cover. When the water returns to a boil, cook until the pasta is not quite done. Drain the pasta reserving 1 cup of water.

In a large skillet, melt 2 tablespoons butter in 2 tablespoons olive oil over medium-high heat. Saute the shallots, garlic, and red pepper flakes (if using) until the shallots are translucent, about 3 to 4 minutes. Season the shrimp with salt and pepper; add them to the pan and cook until they have turned pink, about 2 to 3 minutes. Remove the shrimp from the pan; set aside and keep warm. Add wine and lemon juice and bring to a boil. Add 2 tablespoons butter and 2 tablespoons oil. When the butter has melted, return the shrimp to the pan along with the parsley and cooked pasta and reserved pasta water. Stir well and season with salt and pepper.
