Pesto Sauce

Pesto can be frozen in an airtight container for up to 6 months. You can divide your prepared pesto into the compartments of an ice cube tray and freeze. Once it’s frozen, remove the pesto cubes from the tray and put in a sealable plastic bag or airtight container. You can add the defrosted pesto cubes to soups, pasta dishes, eggs, sandwiches, and potatoes.

For the cheese, be sure to use authentic Parmigiano-Reggiano from Italy; domestic Parmesan is not the same thing. You can always tell if the cheese is authentic by looking at the rind, which is embossed with the name over and over.

For the nuts, walnuts are used instead of the more traditional pine nuts for a few reasons, including cost and avoiding Pine Mouth Syndrome.
