There are a few things that we always have a supply of. Chocolate chip cookies is one. The other is a big thing of pesto in the refrigerator. The key to keeping it fresh is after using it always pour olive oil over the top so it does not spoil.
4 cups basil leaves
1 cup grated Parmesan
1/4 cup pine nuts
1 tsp. kosher salt
2/3 cup olive oil
In a Cuisinart ( makes life easy ) put in the basil, cheese, pine nuts and salt. Blend until really chopped. While the blade is turning slowly add in the olive oil until the pesto becomes more like a sauce. If you need more olive oil, just keep adding until you have the consistency you want.
That's it. Pour in a container, cover with olive oil, leave in the refrigerator for a few weeks. It is good with almost anything.
