- Heat the oil in a large heavy based pan. Soften the onion and leeks, without colouring, adding the garlic, thyme and zest towards the end.
- Add the rice and stir to coat the grains in oil then add in the wine and bubble until almost evaporated. Meanwhile put the water and stock cubes in a pan and bring to a simmer. Stir to dissolve the cubes. This is now your stock.
- Add the stock, a ladleful at a time, stirring constantly. Allow the stock to be absorbed before adding more. Keep adding stock until the rice is tender – about 15 to 20 minutes.
- About 5 minutes before the rice is ready, fry the mushrooms until soft then add to rice. Add a little more stock then pop the lid on the pan. Leave, off the heat, for a few minutes.
- Stir in the parsley, if using, and serve with grated Parmesan cheese.
Tips
Dry Vermouth is a great substitute for wine in cooking. Because it is a fortified wine it keeps for ages after opening. The risotto should be creamy and quite free-flowing when served so add more liquid if necessary.
