The salad is ready, the shrimp have thawed out and the pasta water is boiling.
Put the pasta in the pot of water and stir it right away to keep it from sticking together. Remember to stir it a few times as it cooks.
Put on a skillet that is large enough to handle all the shrimp laid out flat. Set the burner at medium and add the olive oil and 1/2 of the butter. When the butter has melted put in the garlic.
As soon as you get the fragrance of the garlic cooking add the salt, pepper, parsley and red pepper flakes.
