Roe: edible fish eggs — types, uses, preparation, and distinctions

Types and culinary names

Different species produce roe with very different size, color and flavor. The term caviar is traditionally reserved for roe from wild sturgeon and is treated as a luxury item, while other roe have their own names (for example ikura for salmon roe, tobiko for flying fish roe and masago for capelin roe). Roe can be eaten raw, cured, or cooked, and it is an ingredient in many foods worldwide. When mixed into spreads, as in taramosalata, or salted and pressed to make bottarga, roe acquires distinct textures and flavors.

Preparation and preservation

Fresh roe is delicate and perishable. Common processing methods include salting, brining and light curing; some varieties are pasteurized for safety. Other techniques — drying or smoking — produce preserved products with concentrated flavor. In culinary practice roe may be served cooked or raw, depending on the species and the dish; careful handling and refrigeration are important to maintain quality and food safety.

Uses and examples

Roe appears across many cuisines: it is used as a garnish, a textural contrast on sushi, a spread or dip, and a flavorful accent in salads and pasta. Small, crunchy roe like tobiko add snap to dishes, while large, glossy salmon eggs (ikura) give bursts of briny juice. Other regional specialties include cured or pressed roe served thinly sliced, and simple preparations that highlight the roe's natural aroma.

Sustainability, sourcing and distinctions

Some roe-bearing species have been overexploited, which has led to regulation and the growth of aquaculture for sustainable supply. Consumers often look for certified or farmed sources when buying high-value items such as caviar. A noteworthy distinction: "soft roe" or "white roe" is not egg material but the milt or seminal fluid of male fish; this product is considered separate from roe and has different culinary uses and names. For further reading on biological aspects, processing and recipes, follow industry and culinary resources via eggs guides and seafood references.

• Key points: Roe = reproductive eggs; varieties vary by species.
• High-value caviar traditionally comes from sturgeon (sturgeon).
• Remember the difference between roe and soft roe (milt/seminal fluid).
