Most people are familiar with classic Italian pesto, a green sauce made from basil, garlic, pine nuts, Parmigiano-Reggiano, salt, and olive oil. But Leslie Lennox, founder of the award-winning artisanal pesto company Hope’s Gardens, shows us that pesto need not be limited to its original ingredients—and that creative pestos can serve as building blocks for all manner of flavorful dishes, just like any good “mother sauce.”

In Pesto: The Modern Mother Sauce, Lennox introduces readers to a new way to think about pesto. In the right proportion, almost any combination of plants, garlic, nuts, cheese, seasoning, and oil can make a delicious sauce—especially when you’re using what’s on hand, what’s local, and what’s in season.

Lennox offers up several favorite pesto recipes, and then takes these simple sauces a step further. They serve as the building blocks for 97 kitchen-tested recipes for breakfast, lunch, dinner, and more. From risotto and ramen to chicken fajitas and swordfish kebabs, everything tastes better with pesto!
