Truffle And Mushroom Sauce

The star of our truffle usage was without a doubt this wonderful Truffle And Mushroom Sauce that I made to accompany a very rare roast beef fillet. We were lucky enough to be in Italy during truffle season.

For my Truffle and Mushroom Sauce I used Italian Black Summer truffles. These have a rough skin which is created by the stones surrounding them underground. The outer surface is black and the flesh is a pale grey with white marbling. The aroma is like smelling a forest with hints of garlic, wild mushroom and hazelnut. They are harvested in the summer months and are sold when fresh. They can be used to make flavour oil, salt and honey. As they are subtle in flavour you need to shave them just before using, as a finishing element. They are also great to use to infuse sauces, like I have done here, to add depth of flavour. The key is to not overcook the summer truffles and to enhance the flavour, use in cream based sauces. Pair your summer truffles with cheese and eggs, lobster or crayfish, caviar or foie gras or in simple pasta dishes. When cooking consider using garlic, shallots, lightly flavoured vinegars, mascarpone, Parmesan or pecorino, oranges, lemons and soft herbs. Tarragon, basil and rocket work well with summer truffles.
