Bottarga is a delicacy made from the salted and cured roe of fish, typically mullet or tuna. The roe is pressed into a firm block and then dried, resulting in a product that has a rich, briny flavor. It is often grated or sliced thinly and used as a seasoning or garnish in various dishes. This traditional ingredient is popular in Mediterranean cuisine, especially in countries like Italy and Spain. Bottarga can be enjoyed on pasta, salads, or simply drizzled with olive oil and served with bread. Its unique taste adds depth to many culinary creations.
