Galicia loves seafood. The scallop shell is an emblem of their pilgrim walk, the camino de Santiago. I saw a church covered entirely (and beautifully) in scallop shells and many pilgrims with a scallop shell painted with the camino emblem attached to their backpack or their wooden walking stick.
Razor clams are a favourite, as are clams, more pedestrian (but still fabulous) mussels and gnarly percebes, plucked from the cliffs before the waves crash in by expert brave fishermen. If you have been to Spain you will have noticed the percebes, it is hard to imagine that you can eat them that first time they take you by surprise. Black and pointed, looking like a velociraptor talon, not something tender, saline and delicious. Harvested in Galicia and popular in Spain, they are cooked by plunging them briefly in boiling salted water for just a couple of minutes. Pinching them to remove the outer leathery carcass reveals a delicate addictive interior, juicy and bright.
