Well - how do you like it????
Real butter; now - you can roast your garlic and smash it into the butter, or you can mince your garlic and add. That is a basic way of making it. If desired, you can add 1 t. oil (soy, olive, veggie, etc.) (that is for 1/2 c. butter) and fresh minced parsley, fresh minced onions, shallots or chives and a twist (from your pepper mill) of black pepper. If your butter is unsalted you can add salt.
I sometimes will grate Pecorino Romano on top; you can use Parmesan, Romano, Asiago, Fontina - or a blend which is very good also.
Wanna laugh??? Sometimes I will put anchovies on top!!
So you see - it's a great recipe to play with!
