Pesto is an uncooked sauce from Genoa, Italy. The classic recipe calls for lots of fresh basil and garlic pounded together with olive oil, Parmesan cheese and pine nuts. This pesto recipe omits the pine nuts and includes balsamic vinegar and fresh parsley.
Although balsamic vinegar is dark, it's made from the juice of Italian white Trebbiano grapes. Years of aging in wood barrels gives balsamic vinegar its deep, rich color and sweet flavor.
Only one clove of garlic flavors our pesto. For a stronger garlic essence, add another clove or two.
