The recipe for the jams has remained unchanged for years. It is made entirely by hand in small batches using only fresh fruit. Grown organically since the 1980s, the fruit is harvested by hand with production taking place during the winter months, when the fruit is mature and ready to be harvested. The fruit is cut and left to stand for about one day. Then, it is slowly cooked down, adding sugar and lemon juice. No thickeners or preservatives are ever used. The high proportion of fruit, combined with natural ingredients and strict production standards, insure that San Giuliano products have a traditional taste and texture.
