According to a study by the Japanese food community, you need to follow different steps to prepare sea urchins to eat, both cooked and raw.

Let’s take a look at some popular steps to prepare sea urchins.

Easy four steps to prepare sea urchins

Step 1: (Use a pair of sharp kitchen scissors to cut the outer shell)

In the initial steps, you need to turn this globular creature upside-down in a bowl of water.

Now you should use a pair of sharp kitchen scissors to cut the spiky sea urchin’s mouth (all the way around).

Alternatively, you can use a knife to shape it like a mouth if you prefer.

Warning: Be careful while opening, and avoid their spines from entering.

Step 2: (Pull the hard shell gently)

The outer surface of sea urchins is a hard shell. Now, pull the shell gently, flip the urchin into a bowl, and remove the liquid.

Step 3: Invert the urchin back over.

Again, you need to invert the urchin to ensure no residue or visible organs remain. You can use small metal instruments like tweezers to remove the organs (roe or gonads).

Step 4: (Clean the urchin)

When cleaning it, it is suggested to submerge it in a small bowl of ice or saltwater. Ice water can keep the gonads alive and fresh.

To enjoy raw sea urchins, use a spoon to take them from the water bowl. Leave them on a clean kitchen towel and eat them right away.
