How to Cook Percebes: What Are Percebes?
Percebes, or goose barnacles, are one of the ocean’s most unusual and prized delicacies. Clinging to wave-battered rocks on Portugal’s wildest coastlines, these crustaceans are a true treasure of the Atlantic. Though their alien appearance might raise eyebrows, their flavor is pure sea essence—briny, sweet, and unlike anything else. Here is the information you need to know on how to cook Percebes aka Gooseneck Barnacles, for an amazingly fresh seafood appetizer. A taste of Portugal’s rugged coast.
Where Do Portuguese Percebes Come From?
The best percebes in Portugal are harvested along the western and southwestern coasts, especially in areas like:
- Sagres and the Vicentine Coast Natural Park (Costa Vicentina)
- Arrifana and Zambujeira do Mar in the Alentejo
- The Berlengas Islands off Peniche
- The rocky coastline of the Algarve
These barnacles are hand-collected by percebeiros, skilled and daring harvesters who risk their lives climbing slippery rocks at low tide while dodging crashing waves. Because of this high-risk, low-yield labor, percebes are expensive and celebrated as a luxury across Iberia.

Sourcing Percebes in Cascais
On a recent Saturday morning, we picked up a batch of fresh percebes at the Cascais Mercado Municipal. They were sold by weight and kept chilled on ice, as fresh percebes should be. Look for tightly closed shells, plump necks, and a vivid mix of black, gray, and reddish hues—they should smell like the sea and nothing more.

How to Cook Percebes: Keep It Simple
When it comes to preparing percebes, less is more. You don’t need complex seasonings or sauces. Just pure saltwater and a quick boil lets their natural ocean flavor shine.
Ingredients:
- Fresh percebes
- Coarse sea salt
- Water
- Optional: bay leaf
Method:
- Prepare the water: Fill a pot with enough water to cover the percebes and add about 60-70 grams (~1/4 cup) of sea salt per liter. It should be salty like seawater. Add a bay leaf for a touch of aromatics if desired.
- Bring to a boil: Heat the water to a rolling boil.
- Boil briefly: Drop the percebes into the boiling water and cook for only 60–90 seconds. Overcooking will toughen them and mute their flavor.
- Drain and serve: Remove the percebes with a slotted spoon and serve immediately. If they cool, no worries, they are still great to eat!
How to Eat Percebes
Hold a barnacle by the claw-like shell, then gently twist and pull to pop off the leathery outer skin. Inside, you’ll find the tender, pinkish-orange neck—this is the edible part. Be warned: it can squirt salty seawater when opened, so lean over a plate!
The taste is rich and intense, like the distilled essence of fresh shellfish and ocean spray. This quick, easy, yet exquisite dish is the perfect seafood lovers appetizer to enjoy on a warm afternoon after a day at the beach. No butter or lemon is needed—just a cold glass of crisp Vinho Verde, a light Portuguese white wine, pairs beautifully.
Tips and Serving Ideas:
- Serve immediately after cooking—percebes are best hot and freshly boiled.
- Pair with: crusty bread, boiled potatoes, or a crisp green salad.
- Drinks: In addition to Vinho Verde, try an Albariño from northern Portugal or a dry sparkling wine.
