Fiskurkaka (fried fish cakes)

Instructions

1. Finely chop the fish with a knife or in a food processor, without turning it into a purée.
2. Mince the onion very finely and mix it with the fish, the beaten egg, the flour, the milk, the salt, the sugar and the pepper.
3. Shape the patties by hand to about 1 cm thick and 7 cm across.
4. Heat the oil in a thick-bottomed pan to 170 °C, or until a small piece of the mixture sizzles vigorously.
5. Fry the patties for 3 to 4 minutes per side until a nice golden colour.
6. Drain on kitchen paper and serve hot with lemon wedges.
