Really simple and delicious. I added a splash of cream and chicken stock to go with half the recommended amount of pasta water and stirred vigorously over the heat to emulsify everything, then squeezed a lemon over it to taste (something about the creaminess of the sauce just needed a little acid to brighten it up). This would also be good with some cherry tomatoes thrown in with the garlic or some white wine for that same bright flavor.
