Everything You Need to Know About Eating Sea Urchin

At first glance, this dark and spiky sea creature might look more frightening than delicious, but sea urchin is a seafood delicacy enjoyed all around the world. Even right here on the west coast of the United States, we have access to some of the world's best sea urchin uni. Uni is the name for the five bright orange, edible, and delicious organs inside the spiky sea urchin shell. Uni are the gonads of the sea urchin, the reproductive organs responsible for forming the sea urchin roe, otherwise known as sea urchin eggs. Sea urchin is a little different than other fish in that you don't necessarily want to eat the roe, but you want to eat the uni before they fill up with eggs.
Beyond its unique taste and texture, sea urchin is packed with essential nutrients that our bodies need. It is rich in protein, omega-3 fatty acids, and various vitamins and minerals. A 100-gram serving of sea urchin provides about 172 calories, 14 grams of protein, and a significant amount of vitamin A, vitamin C, calcium, and iron. The omega-3 fatty acids found in sea urchin help promote heart health and reduce inflammation, making it a nutritious choice for seafood lovers.
You can enjoy eating sea urchin in many different ways. Most often, people worldwide want raw sea urchin sushi, but uni sushi isn't the only way to eat uni. Many chefs mix uni into soups, sauces, and other dishes for its unique and salty flavor and creamy texture.
Let's dive into this unique seafood and discover all things uni sea urchin.
Diving for Sea Urchin
Sea urchins are one of the few creatures in the ocean that divers still harvest by hand. Free divers dive to depths as far as 50 feet deep to harvest sea urchins off rocks on the ocean floor.
The sea urchin you eat in the US most likely comes from the Pacific Ocean off the west coast of California, although sea urchins are found throughout the world's oceans. We find that the sea urchin from the west coast has a much more pleasant flavor. It's also larger! When eating west coast sea urchins, you still taste the ocean, but in a delightful umami sense. The mild briny flavor is like that of oysters or other raw shellfish.
East coast sea urchins are smaller and have a much stronger flavor. Currently, Atlantic sea urchins are protected from harvesting after decades of overfishing.
Sea urchins are a culinary experience with something to offer each of your senses, from its bright color to its creamy texture and mild ocean flavor.
A Story of Sustainability
Sea urchin is one of the most sustainably fished sea creatures you can eat. The hand-harvesting technique ensures the seabed and other habitats remain undisturbed, and there is virtually no accidental bycatch when divers cut sea urchins from their rocky underwater homes.
In Jeju Island, off the coast of South Korea, women train to become sea urchin divers. These women, called Haenyeo, dive and hold their breath for long periods to harvest sea urchins and other seafood delicacies. These women can support their families from the money they earn diving for sea urchins. Haenyeo women have passed on the diving tradition for centuries. Mothers, daughters, and grandmothers dive to treacherous depths to improve the economy of their villages.
For such an unsuspecting-looking sea creature, they sure do provide food and livelihood for many people.
An Invasive Species?
In parts of the world, sea urchins are an invasive species. So, what does that mean? Invasive species are animals that are not natural to the habitat they have moved to. They can do more harm than good to the world's oceans.
So, what is it that the sea urchins are doing?
Sea urchins eat kelp and other seaweed as their primary food source. Kelp is an underwater plant that captures and stores CO2. Mature sea urchins have very few predators because of their hard spiky shells. Only humans and the occasional sea otter venture to the rocky ocean floor to feast on sea urchins. Too many sea urchins mean less and less kelp on the ocean floor.
Luckily for us, kelp recovers quickly, and sea urchins aren't an endangered species. A healthy balance of sea urchin harvesting can protect the ocean's kelp, which is better for the ocean environment!
So, you can feel good about buying and eating sea urchins for sale! You're doing the oceans a favor!
What Does Sea Urchin Taste Like?
If you've never tried sushi uni before, but you love oysters and other raw seafood, you're in for a real surprise when you taste the natural sweetness and saltiness of uni food.
Uni sushi has a mild flavor, soft custard-like texture, and natural sweetness like oysters or scallops. Sushi sea urchin is raw urchin uni. You can enjoy this delicacy by itself, in sushi, or over pasta for a nice punch of ocean flavor.
Many divers enjoy uni right out of the ocean after cleaning off all the sand. Otherwise, divers harvest the uni and store them in saltwater to preserve the fresh taste and texture.
The unique texture of sea urchin uni changes depending on the season. The best time to harvest sushi sea urchin is before the uni has filled with eggs or roe. Once the urchins have matured and developed their eggs, the uni becomes hardened, making the texture less pleasant. The best time to enjoy uni is from March to November.
