In a heavy-bottomed saucepan, combine the chopped shallots, finely grated truffles, white wine and reduce until syrupy.
Add the rice and let it become slightly translucent, then add a little of the heated stock. Cook, watching and stirring frequently. Add the hot stock a bit at a time until it is absorbed.
Serve in warm ramekins or on warm plates.
Notes
Use vegetable stock for a meat-free option. You may need more or less stock depending on the brand of risotto.
