Cod With Spiced Red Lentils

Put the lentils in a saucepan with the turmeric and stock. Bring to the boil, cover with a tight-fitting lid and simmer for 20-25 minutes, until the lentils are just tender. Remove from the heat and add salt.
Heat the oil in a small frying pan. Add the cumin seeds and, when they begin to pop, add the ginger and cayenne pepper. Stir-fry the spices for a few seconds, then pour on to the lentils. Add the lemon juice and the coriander and stir them gently into the mixture.
Lay the pieces of cod on top of the lentils, cover the pan and then cook gently over a low heat for 10-15 minutes, or until the fish is tender.
Serve garnished with chopped coriander leaves and one or two lemon wedges.
