5: Pour 6 tablespoons olive oil into a large pan on medium heat. When hot, add the onion, garlic and herbs, salt and pepper. Cook for 5 minutes, stirring frequently. The onion should just colour a little.
6: Tip in 350 g rice and stir constantly for 4 or 5 minutes. The rice should be well coated with oil and slightly 'pearled'.
8: ... and stir until completely absorbed by the rice. Remove the herbs and discard.
9: Add a little vegetable stock...
10: ...and stir until completely absorbed by the rice.
11: Repeat this operation, a little at a time, intil all the stock has been used up.
12: Stop when the rice is cooked to your taste and still a little moist. A risotto should never be completely dry. This whole process is supposed to take 18 minutes, but this will depend on a lot of things (type of rice, intensity of cooking, etc.), and it is best to expect it to take nearer 30 minutes.
13: Once the rice is cooked, it is time for the mantecare: tip 2 tablespoons Mascarpone and the grated 100 g Parmesan (Parmigiano Reggiano) into the pan. Take off the heat, cover and leave to rest for 4 minutes.
14: After this time, uncover and mix thoroughly to ensure that the mascarpone and Parmesan are well mixed in.
15: To finish, add the peas, mix once more, cover and leave to rest for a further 2 or 3 minutes until the peas have heated through.
16: Your risotto is ready.
Remarks
For an authentic Italian touch, try to find `carnaroli' rice if you can. You can replace the vegetable stock with chicken stock if you prefer (a simple stock cube dissolved in hot water).
