4 cups/1 liter chicken stock
6 fresh shiitake mushrooms, finely sliced (or 6 dried ones — see note)
150 g/5.3 oz mixed wild mushrooms, finely sliced
2 tablespoons/30 ml vegetable oil (for frying the mushrooms and onions)
1 onion, finely chopped
2 tablespoons/30 ml olive oil (for the risotto)
150 g/5.3 oz Arborio rice
⅔ cup/150 ml white wine
1 tablespoon/15 ml truffle trimmings (optional or use 1 teaspoon/5 ml truffle oil)
½ cup/125 ml Parmesan cheese, finely grated
¼ cup/60 ml chives, finely chopped
salt and freshly ground black pepper
If using dried shiitake mushrooms, pour out 1 cup/250 ml of the stock into a bowl containing the dried mushrooms. Set aside to soak until soft. Keep the rest of the stock simmering for the risotto. Remove the soaked mushrooms from the soaking liquid and finely slice them. Strain the soaking liquid of the mushrooms into the simmering stock.
In a medium saucepan, bring the stock to a simmer.
In a clean saucepan, heat the vegetable oil, then add all the mushrooms and onion and fry until cooked. Remove from the saucepan and set aside. (If using the dried shiitake mushrooms, strain at this stage and slice finely, then add it to the pan with the other mushrooms).
Wipe the saucepan and heat 2 tablespoons/30 ml olive oil, then add the rice and stir to coat until it is lightly toasted but not colored. Add the wine and bring to the boil until all the alcohol has evaporated — stirring occasionally. Stir in half a cup of the stock and cook until almost all the liquid has been absorbed. Keep stirring occasionally. Continue adding the remaining stock, half a cup at a time, to the rice until almost all but half a cup of stock remains. This should take about 25 minutes. Add the cooked mushrooms, the onions and the balance of the stock. Stir to heat through. Remove from the heat, stir in the truffle trimmings (or truffle oil), the cheese and chives, and season to taste. Serve immediately.
