Sea urchin (French: oursin) is a spiny marine animal whose edible portions are the reproductive organs, commonly called gonads or roe in culinary language. In Japanese cuisine, the edible portion is known as uni. It has a soft, creamy texture and a briny, sweet, ocean-like flavour. Colour ranges from pale yellow to deep orange depending on species, maturity and condition.
The edible sections are delicate and are usually removed from the shell and packed in trays. Sea urchin is commonly served raw in sushi and sashimi, on toast, with pasta or in sauces. Its flavour is easily overwhelmed by strong seasoning, so simple preparations often work best. It can also be gently incorporated into warm sauces, but excessive heat may cause the texture to break down.
Sea urchin is highly perishable and should be purchased from an approved supplier with clear species, harvest-area and handling information. Confirm whether the product is fresh, frozen or processed, and check its pack date and use-by instructions. Keep it refrigerated at the supplier-recommended temperature, protect it from contamination and use it within the stated shelf life.
Example: serve a small portion of uni over sushi rice, on a warm toast point or folded into a butter sauce for pasta.
Its natural sweetness and salinity vary, so taste before adding salt, acid or fat. Lemon, citrus zest, light dashi, butter and restrained herbs can complement sea urchin without masking its character.
Food-safety note: Do not assume a fresh appearance guarantees safety for raw consumption. Follow local requirements and supplier guidance, and take extra care when serving raw seafood to higher-risk guests.
Allergen note: Sea urchin is an echinoderm, not a crustacean or mollusc, but it is still seafood and must be identified clearly for guests.
