1.In a large saucepan of boiling, salted water, cook potatoes 12 minutes, until easily pierced with a fork. Drain and return to pan. Heat on low for a few minutes, until thoroughly dry. Mash well.
2.Flake salmon into a bowl. Mix in mashed potato, onion, curry paste and coriander. Season to taste. Shape into 8 cakes. Dip each cake into flour, brush with beaten egg and coat with breadcrumbs. Chill.
3.In a large frying pan, heat oil on medium. Fry patties in 2 batches, until golden and heated through. Serve with lemon wedges, chutney and salad.
For a vegetarian version, omit salmon and add leftover cooked vegetables, cut into small pieces.
