The aromatic red grapefruit has become a staple of Italian fruit stands. This exquisite marmalade, with its clean, bright flavor, fresh citrus aroma and tiny bits of pulp, is one of San Giuliano’s best. Swirl it into oatmeal and yogurt, or whisk it into a salad dressing. Sweet and tangy, it complements soft, creamy cheeses like goat cheese or sheep’s milk ricotta.
