1.
Heat the oil in a large, heavy-based pan over a moderate heat. Stir in the onion and garlic and cook gently for 4–5 minutes until softened but not browned, stirring occasionally.
2.
Stir in the rice, pumpkin or butternut squash and sage leaves and cook for 2 minutes longer. Stir the saffron into the hot stock, then pour about a quarter of the stock into the pan and stir well until it has almost all been absorbed, stirring frequently.
3.
Continue adding the stock, only a ladleful at a time, making sure each is almost completely absorbed before adding the next, and stirring frequently to produce a creamy texture.
4.
With the last addition of stock add the sweetcorn and stir well. Once all the stock has been absorbed and the rice is tender (this will take about 20 minutes), stir in the mozzarella cheese.
5.
Season to taste, then cover the pan and allow to stand for about 5 minutes. Sprinkle the risotto with the pumpkin seeds and serve at once.
variations
In summer you can replace the pumpkin with courgettes. Cut these into small pieces and add to the risotto with the sweetcorn in step 4 as they do not need a long cooking time.
cook's tip
The secret of a good risotto lies in using the right rice – arborio, carnaroli or vialone nano – and a well-flavoured stock that should be added gradually.
