Can You Eat Barnacles?

Barnacles are often seen clinging to the undersides of boats and rocks, but did you know that these seemingly unremarkable crustaceans are actually edible? In this article, we’ll dive into the world of barnacles, exploring their culinary potential, how they’re prepared, and their nutritional benefits. If you’re curious about trying barnacles or just want to learn more about them, read on!

What Are Barnacles?

Barnacles are marine crustaceans that attach themselves to a variety of surfaces, including rocks, ship hulls, and even whales. Unlike most crustaceans, barnacles have a unique, hard shell and a filter-feeding mechanism that allows them to catch plankton and small particles from the water. This distinctive appearance and feeding habit make barnacles a fascinating subject in marine biology.

Types of Edible Barnacles

There are several species of barnacles that are considered edible, but the most commonly consumed are gooseneck barnacles and acorn barnacles.

Gooseneck Barnacles

Gooseneck barnacles, or Pollicipes polymerus, are known for their long, slender stalks resembling a goose’s neck. They are highly prized in Mediterranean cuisine, particularly in Spain and Portugal, where they are called percebes. The flesh inside the shell is tender and flavorful, with a taste that some describe as a cross between crab and sea urchin.

Acorn Barnacles

Acorn barnacles, or Balanus species, are smaller and more common than their gooseneck counterparts. While not as sought after as gooseneck barnacles, they are still consumed in various regions, particularly in the United Kingdom. The taste of acorn barnacles is milder, and they are often used in soups, stews, or simply boiled.

How to Prepare Barnacles

Preparing barnacles might seem intimidating, but it’s quite straightforward once you get the hang of it. Here’s a basic guide to preparing barnacles for cooking:

Cleaning: Rinse barnacles under cold water to remove any debris. For gooseneck barnacles, you may need to trim the stalks if they are particularly long.
Cooking: Barnacles can be steamed, boiled, or grilled. To steam or boil, cook them for about 5-7 minutes until the shells open. If grilling, brush them with olive oil and grill for a few minutes on each side.
Serving: Serve barnacles with a squeeze of lemon or a drizzle of olive oil. They can be enjoyed on their own or as part of a seafood dish.

Nutritional Benefits

Barnacles are not just a delicacy; they also offer several nutritional benefits. They are rich in protein, low in fat, and packed with essential vitamins and minerals, including vitamin B12, zinc, and iodine. Additionally, barnacles are a good source of omega-3 fatty acids, which are beneficial for heart health.

Potential Health Risks

While barnacles are nutritious, it’s important to be aware of potential health risks. As with any seafood, ensure that barnacles are sourced from clean waters to avoid contamination with pollutants or toxins. Also, individuals with shellfish allergies should avoid barnacles, as they may trigger allergic reactions.

Where to Buy Barnacles

Finding barnacles can be challenging depending on where you live. Specialty seafood markets and high-end grocery stores are your best bet. Additionally, some online seafood suppliers offer fresh barnacles that can be delivered directly to your home.
