Percebes Gallegos Cocidos

Percebes cocidos are Galician, especially of the wave-beaten Costa da Morte, and Galicia serves them with nothing to hide them. The barnacles go into fiercely salted boiling water, come out almost at once, and reach the table bare. No oil, no lemon, no sauce. The sea has already seasoned them.

The method that decides the dish is an old Galician rule: auga a ferver, percebes botar; auga a ferver, percebes sacar. Water boiling, barnacles in; water boiling again, barnacles out. That brief, fierce heat sets the flesh while leaving the stalk tender and full of its own briny liquor. Let them boil on and they turn firm and dry. There is no rescue after that, so stay beside the pot.

Far from Galicia, buy legally harvested Atlantic percebes from a specialist fishmonger. If those cannot be found, responsibly harvested Pacific gooseneck barnacles are the nearest honest substitute. Their stalks are often longer and firmer, and their flavor is less concentrated, but the same boiling rule holds. Serve them under a damp cloth, twist one open with your fingers, and mind where you point it because the first may squirt. Siempre sale, si lo sigues. The Margin beside this recipe carries only that boiling rule. It needs no more.
