AT A GLANCE
There are several types of risotto rice. The easiest to find is arborio; it needs the least cooking time and tends to break down easily. We've used carnaroli here, which is worth seeking out - it holds its shape nicely.
|01||Soak porcini in a bowl with 700ml boiling water for 10 minutes to soften. Drain, reserving stock. Finely chop mushrooms and reserve. Keep stock warm.|
|02||Meanwhile, heat half the butter and half the oil in a saucepan over high heat, add fresh mushrooms and sage and sauté until tender and golden brown (3-5 minutes). Set aside. Add remaining butter and oil to pan along with onion and sauté until golden brown (4-5 minutes). Add rice and stir to coat in oil, then add wine and simmer until evaporated (1 minute). Add reserved stock a ladleful at a time, stirring continuously between additions until most is absorbed before adding the next, until rice is al dente and creamy (13-15 minutes; you may not need all the stock). Season to taste, stir in mascarpone, parmesan and three-quarters of both mushrooms, then serve risotto topped with remaining mushrooms and extra grated parmesan.|
