Wild risotto

Bring the stock to the boil in a large saucepan and keep it simmering. Meanwhile, heat the oil in another large saucepan and fry the onion until soft and just starting to colour. Add the arborio rice and cook for 2 minutes, stirring all the time. Pour in the wine and cook for 5 minutes. Start to add the stock using a large ladle. Cook gently, stirring regularly and making sure all the stock has been absorbed before adding the next ladle full. This should take about 25-30 minutes . While the rice is cooking, cover the ceps with boiling water and soak for about 15-20 minutes. Drain, reserving the soaking liquid and chop. Heat the butter/vegan margarine in a frying pan and quickly cook the sliced wild mushrooms for about 5 minutes. Add all the mushrooms to the rice together with the two cooked wild rices and the reserved soaking liquid. Add a little more stock if necessary and heat through thoroughly. Remove from the heat and if using, stir in the pecorino cheese. Season to taste and serve immediately.
