Black treacle cured salmon is a delicious and flavorful dish that combines the richness of salmon with the sweetness of black treacle. The treacle acts as a marinade, infusing the salmon with a deep, caramelized flavor. The curing process also helps to preserve the fish and give it a firm texture. This dish is perfect for a special occasion or as an impressive appetizer. Serve it thinly sliced on a platter with some crusty bread and a tangy mustard sauce for a delightful culinary experience.
