If I have too much fresh basil, cilantro or parsley, I freeze it. With a knife, I chiffonade or chop the leaves, put them in an ice cube tray, cover with olive, coconut, canola, oil of choice and freeze. Release them into a freezer bag. As many individual cubes as needed can be used in sauces, soups, etc. I make pesto with the cubes, rather than make pesto and freeze it. Typically, pesto contains pine nuts. They're pricey. I use toasted almonds. I've got an old 4-cup Oster mini-chopper and prefer using it to the blender,
