Boil 4 cups of water.
Add salt and a teaspoon of olive oil.
Add pasta.. This is good for small pastas (rotelle, penne etc)
Make a butter sauce by melting butter, garlic salt and pepper over a low flame.
For the pepper, I highly recommend freshly ground coarse pepper.. You can take a handful of whole peppercorns and then put them on a cutting board, and use a heavy skillet to coarsely grind them.
Drain your pasta when al dente and add the butter sauce.
Mix and serve with grated cheese.
