   Fill a large pot with mineral water and add 60 g of salt per litre, plus 2 or 3 bay leaves if you like. Bring it to the boil.

   Put the clams and mussels in a pan with about two finger-widths of water. Bring to the boil, wait about 2 minutes for them to open, then take the pan off the heat.

What is a Galician seafood platter?

A seafood platter is an assortment of shellfish and crustaceans cooked simply and served together, often as a centrepiece for sharing. In Galicia, Spain’s north-western coastal region, seafood is a familiar part of the local food tradition.

This version combines lobster, langoustines, prawns, goose barnacles, clams and mussels. Cooking the different types in stages helps each one reach the table without being left in the pot too long.

Nutrition and macros by portion

The nutrition label shows one serving as written: 635 calories, 133g protein, 2g carbs, 11g fat.

The listed nutrition per serving is dominated by protein from the lobster, langoustines, prawns and shellfish. The seafood also accounts for most of the fat, while the listed carbohydrate content is very low. Serve with vegetables or salad and bread if you want a more substantial, balanced plate.

Salt and bay in the cooking water

Salted water: the recipe specifies 60 g of salt per litre, so measure the water before seasoning it. Use a large pot with enough room for the lobster and later additions.

Bay leaves: add 2 or 3 to the water if you want a gentle herbal note. They are optional and can be left out without changing the cooking sequence.

Cook each seafood in stages

Lobster: the stated timing is for one weighing around 1 kg, with the 20 minutes counted only after the water returns to the boil. A different-sized lobster may need a different cooking time.

Crustaceans: add the langoustines and prawns after the lobster, cooking them for 4–5 minutes. Goose barnacles go in last for just 1 minute, so they are not left boiling while the other seafood cooks.

Prepare the clams and mussels separately

Clams: clean them well before cooking, as directed. Their cooking time is brief: about 2 minutes in a separate pan with a little water, until they open.

Mussels: scrub off any attached crustaceans and remove the beards, then soak them in cold water for at least 1 hour. Cook them with the clams and take the pan off the heat once they have opened.

Watch for the doneness cues

Timing: use the recipe's timings as a guide, and keep the pots under observation rather than leaving seafood to cook unattended. In particular, remove the clams and mussels from the heat once open.

Texture: the method keeps cooking brief for the smaller seafood, which helps avoid leaving it in boiling water longer than needed. Arrange the cooked pieces on the platter carefully so they remain intact.

Serve it as a shared meal

Platter: distribute the seafood across a wide serving tray so the different pieces are easy to reach. Serve it once everything is cooked, rather than letting the shellfish sit in its cooking water.

Accompaniments: offer bread and a simple salad alongside, if desired. Keep extras separate so they do not cover the seafood's delicate flavour.

Recipe notes & tips

• Measure the water before adding salt so you can follow the specified 60 g per litre.
• Start the lobster's 20-minute timing only once the water has returned to the boil.
• Keep the goose barnacles aside until the final minute of cooking.
• Soak the mussels in cold water for at least 1 hour before cooking.
• Take the clams and mussels off the heat as soon as they open.
• Use a wide platter to make the assortment easier to serve.

Variations

• Skip the bay: leave out the optional leaves for a plainer cooking liquor.
• Serve with lemon: add lemon wedges at the table for a fresh, sharp contrast.
• Add a salad: serve crisp salad alongside for a lighter accompaniment.
• Offer bread: put bread on the table to accompany the seafood.
• Change the platter: arrange the seafood in separate groups so diners can choose what they like.

Common mistakes to avoid

• Starting the lobster timer too soon: count the 20 minutes from when the water returns to the boil.
• Cooking the barnacles too early: add them at the end because they need only 1 minute.
• Skipping the mussel cleaning: scrub off attached crustaceans and remove the beards before cooking.
• Rushing the soak: leave the mussels in cold water for at least 1 hour.
• Overcooking the clams and mussels: remove the pan from the heat after about 2 minutes, when they have opened.

How to store

Seafood is best served freshly cooked. Refrigerate any leftovers promptly in a covered container and use within 1 day; reheat gently until hot, or serve chilled if appropriate. Discard shellfish that remained closed after cooking.
