This recipe adds a luxurious twist to the classic Sarde a Beccafico by incorporating saffron and raisins into the stuffing for the sardines. The saffron adds a floral and slightly bitter flavor, while the raisins provide a sweet note. The sardines are stuffed with a mixture of breadcrumbs, saffron, raisins, pine nuts, and olive oil. The dish is then baked until the sardines are crispy and the stuffing is golden brown.
