Karpfen blauCarp poached in vinegar stock
In Franconia and Bavaria, Christmas Eve supper is often carp, and the old way is 'blau': the fish is poached in a sharp vinegar stock that turns its natural skin slime a striking slate blue. It is served with melted butter, freshly grated horseradish and boiled potatoes, and many families keep a carp scale in their wallet for good luck in the year ahead. Buy carp already killed and gutted by the fishmonger, and ask for it unscaled and handled as little as possible, or the blue colour won't appear. Chef's tip: never rinse or wipe the carp skin, because the slime is what turns blue.
