This beloved green basil sauce originated in the Liguria, Italy. Now, the Northern Italian superstar, pesto, is popular worldwide as a fresh (no cook) pasta sauce and colorful condiment. Gaining popularity in recent years, this herbaceous staple of Mediterranean cuisine is perfect for pairing up with a wide array of foods and recipes. Add just a spoonful to your favorite dishes for a bright burst of sweet basil. Though pesto isn’t quite as popular as, say, mayonnaise or mustard, it’s quickly finding a home in every chef’s kitchen.
