Preparing the custard, use truffle oil as an alternative of olive or oil, whisking it collectively along with your standard egg mixture; in the meantime, mix cream, milk, and soy sauce in a small saucepan, bringing them simply to a boil before removing them from heat for brisk mixing with the egg combine. Put one-half of the sauce on the beneath side of toast; put toast on a small baking dish, pile mushroom caps cleaned and pealed in conical form on toast, and pour over cream. This white truffle has a skinny buff coloured pores and skin, and might be slightly knobby with a marbled toffee & cream to darkish coffee coloured interior when ripe. Ground nutmeg. This will go into the cream cheese filling and be sprinkled on high of the completed white chocolate truffles.
