Kæst skataFermented skate
St Thorlak's Day (Þorláksmessa), 23 December, honours Iceland's patron saint, and in the Westfjords and now across the country it is the day for kæst skata: fermented skate, boiled and eaten with potatoes and melted, salty sheep's tallow (hamsatólg) or butter. Its ammonia smell is famous, which is why many families cook it in the garage or eat at a restaurant, then have it the next day as a bracing start to Christmas. Buy skate already fermented from an Icelandic fishmonger; don't try to ferment it at home. Chef's tip: cook it in a lidded pot with a window open, and boil the potatoes in a separate pot.
