This signature and best-selling Genoese pesto recipe is made with sunflower seed oil, 100% Italian basil, extra virgin olive oil, cashews, Grana Padano DOP and Pecorino Romano DOP cheeses. Each Nord Salse recipe is designed to achieve the perfect balance of flavors and nutrients. Sunflower seed oil is used because it lends a delicate note, makes the pesto light, and helps keep prices low.
