Drain clams - reserve 1 1/2 cups liquid (if you don't have that much, just add water to make 1 1/2 cups or you can use bottled clam juice) - set aside. Heat butter and oil - add garlic - saute until golden - do not brown the garlic - it will become bitter (approximately 6 minutes). Stir in parsley, salt and clam liquid. Bring to a boil - add clams and simmer an additional 3 minutes.
Pour over cooked pasta of your choice - linguini and spaghetti work very well.
