Pesto Sauce - cooking recipe

Ingredients

100 basil leaves
1/3 - 1/2 cup olive oil
1/2 parmigiano-reggiano cheese (very expensive, but worth it)
2 tablespoons pignolis

Preparation

Place basil, cheese and nuts in food processor or blender.
Pulse a few times.
Stream olive oil through feed tube until desired consistancy is achieved--I usually use a little more than a 1/4 cup of oil.
Toss with hot cooked pasta or use as a spread.
