Galician gooseneck barnacles, known as percebes, are among the most prized seafood in Spain, and for good reason: their intense, irresistible marine flavor makes them a true delicacy. This recipe gives you the keys to cooking them perfectly at home with nothing more than salted water.
The preparation couldn't be simpler. The only real secrets are starting with excellent product and avoiding overcooking. There's also a clever trick: cooking them in several batches so the flavor of the barnacles builds in the water and each batch tastes even better.
Gooseneck barnacles are served hot, brought to the table wrapped in a napkin to keep them warm until eaten. That's why it's important to cook them immediately before serving—this isn't a seafood you can prepare ahead of time. Let's get to it!

Ingredients for Gooseneck Barnacles
Serves 2
- 400 g gooseneck barnacles (percebes)
- Water
- Salt

How to Make Gooseneck Barnacles Step by Step
1. Boil the salted water and add the barnacles
First, bring plenty of salted water to a boil, using 60 g of salt for every 1 liter of water. When the water starts boiling, add the barnacles.

2. Cook until a rolling boil returns
As soon as you see a steady boil again, the barnacles are done. Be careful not to overcook them—the secret is a good product and just the right amount of time in the water.

3. Remove from the water
Remove the barnacles from the water and transfer them to a serving dish. Cover them with a cotton cloth to keep them warm.

4. Serve hot
Your delicious, exquisite gooseneck barnacles are ready. Bring them to the table covered with the cotton cloth so they stay hot until the very moment you eat them.

Tips for the Best Gooseneck Barnacles
Cook in batches for deeper flavor
If you're cooking a larger amount, cook the barnacles in several batches. The flavor of the barnacles stays in the cooking water, so each batch will taste even richer than the last.
Don't overcook them
The key is to pull them out as soon as a steady boil returns. Overcooking makes them tough and rubbery, so keep a close eye on the pot.
Serve them immediately
Gooseneck barnacles are at their best hot, straight from the pot. Cook them just before serving and keep them wrapped in a cotton cloth at the table so they stay warm.
