Fish cakes are an excellent way to use up leftover mashed potato, and this recipe uses Thai curry paste and chilli to give them a gorgeous Asian spicy flavour.
These spicy salmon fish cakes can be made a day ahead and chilled in the fridge overnight, then freshly fried when you are ready to eat them.
Mix the mashed and grated potatoes together in a large bowl. Stir in the Thai green curry paste then the flaked salmon, the spring onions, chillies, coriander and garlic. Season with a little salt and pepper.
Divide the mixture into six and using wet hands, shape them into round patties, about 1cm thickness.
Set up three plates or shallow bowls. Put the beaten egg in one, use one for the flour and one for the polenta.
First roll the cakes in the flour, then dust off any excess. Next roll them in the egg and finally in the polenta to coat.
Heat a little vegetable oil in a large frying pan. Place the fish cakes in the hot oil and fry for 3-5 minutes on each side, until golden.
