Pesto

Put the basil, olive oil, pine nuts, garlic cloves and salt in the blender; mix at high speed.

Stop from time to time and scrape the ingredients down toward the bottom of the blender with a rubber spatula.

When the ingredients are evenly blended, pour in the cheeses and blend until the mixture is smooth.

If pesto is too thick, add to it a tablespoon or so of the hot water in which the pasta has boiled.

Pour the pesto sauce over your favorite hot pasta.
