This is a lovely rice salad with optional truffles! Other ingredients include lemons, anchovies, white wine and garlic. Many people object to the combination of truffle and lemon, claiming that the delicate flavour of the truffle should be protected from something as harsh as lemon juice. I think they marry very well indeed in some dishes and this is one of them. It is a recipe from Novara, in whose province stretch endless rice fields.
