Shrimp scampi is basically just shrimp, wine, garlic, butter and lemon. I like a lot of sauce, especially to toss with pasta. I cooked the shrimp shells in some wine and water to give me a little stock. Just let it simmer on the stove while you prep the rest of the ingredients. And I reserved some pasta water. The wine, stock and pasta water provide an ample amount of sauce for the linguine and shrimp.
