Meanwhile, put the salmon fillets, skin side down into a non-stick frying pan.
3. Add the potatoes, harissa, coriander, preserved lemon, spring onions and egg to the bowl with the fish. Season with salt and mix together really well. Shape into 4 fish cakes. Place onto an oiled plate and pop them into the fridge to firm up for 15 minutes.
4. Tip the semolina into a shallow dish. One at a time, dust the fish cakes all over so they get completely covered in the semolina.
Heat the oil in a non-stick frying pan over a medium heat and add the fishcakes. 5. Fry for 4-5 minutes each side until golden on the outside and warm in the middle. Serve immediately with mayonnaise.
