Sea urchins are enjoyed in a variety of ways—both raw and in prepared dishes. Due to it’s delicate taste, they are best served with foods that have a neutral flavour, such as pasta or toast. But how exactly does it taste? Those who have tried one often have a difficult time describing the taste. It has a sweet, yet subtle, fresh-from-the-ocean flavour and is often compared to oysters.

How to Dive for Sea Urchin

If you’d like to try fresh sea urchin without paying restaurant prices, you can dive for your own!

They’re most commonly found in rocky coastal areas and have small tube feet that allow them to cling to rocks. In addition to basic diving gear, bring along a knife or a pair of gloves to help your pry one from the rock. [clickToTweet tweet=”Eating sea urchin? Avoid ones that are pitch black in colour.

You’ll want to avoid sea urchins that are pitch black in colour. Instead, always search for ones that have hints of green, purple, and/or red. Black sea urchin often appear in photos, but this is more for decorative purposes or as a result of bad lighting.

How to Prepare Sea Urchin

The key to enjoying fresh, delicious sea urchin, or uni as it’s called in Japan, is to separate the orange meat from the internal walls of the spiny shell. These five orange pieces are actually the reproductive organs of the sea urchin.

Keep in mind that not all sea urchins are created equal. You’ll likely notice that it looks and tastes differently depending on which part of the world you’re in. In total, there are 18 edible varieties and their meat differs in texture, taste, and colour.

In order to protect yourself from the spikes, it’s recommended that you wear gloves. If you don’t have gloves on hand, at least be cautious. When you are ready, gently pick it up.

Next, create a puncture in the underside (i.e. the flatter side) of the sea urchin using scissors, a bread knife, or a spoon. Allow the liquid to drain out and slowly cut a circle in the bottom part of the shell. Remove the base and carefully take out the black, internal pieces—this part is not consumed.


You can also gently rinse out the inside with running water. Once you’ve cleaned out the inedible parts, focus on the five orange pieces attached to the top of the shell—these are what hold the sea urchin’s delectable flavour.

Lastly, using your fingers or a utensil, gently scrape out this part and voila! It’s ready for eating or preparation.

How to Enjoy Sea Urchin

The most common way to enjoy sea urchin is by eating it raw, similarly to how one would enjoy oysters or sushi. Adding butter or lemon juice is a great way to enhance the natural flavour.

Chefs around the world also use sea urchins as a way to add a unique twist to traditional dishes. In the Mediterranean, chefs serve them as an addition to pasta. In some places, they’re served with butter and toast. The possibilities are endless—sea urchin can be a flavourful and savoury substitute for lobster, shrimp, and other popular seafood!

Eating bad sea urchin can seriously affect your experience. Sea urchin should taste like the ocean, but it should never taste fishy. If it does, it’s likely gone bad.

    You need gloves or a towel to hold the urchin, then crack the top around it to expose the 5 tongues. Remove with your hand from
    center as one unit maintaining the star shape without damaging the individual tongues. In Chile sea urchins are a fresh delicacy,
    mainly from Puerto Montt in the South. Toast and white wine are the best pairing. Further South, in Chiloé they prepare the sea
    urchins “al cajón”, spread inside a loaf of bread keeping just the outside crust and then to the oven…delicious!

    I grew up eating huge spiky black sea urchins in tropical South America. Most of the dirt-poor kids in my seaside shantytown community harvested them during low tides that exposed them in shallow natural puddles and small pools. We lit up an open fire using dry organic beach matters, briefly roasted them alive, and ate them on the spot sitting on the sand under a palm tree. Note to Chefs everywhere: Best gourmet taste ever if same conditions can be replicated…. Alas, for us then half-starved kids, sea urchins were just a much-needed supplement to the meager diet our families could afford. Grateful for them!

    When I was a young
    boy grown up in the Caribbean my friends and I used to dive for the black and white ones and collect a bunch when finished diving we’d divide them and eat them on the beach right there.

    To open urchins easily, and have a pretty “bowl” to serve them in, I use a holesaw in my cordless drill. It also result in a craftable shell.
