Please read Truffles before making this recipe. True truffles are expensive and rare, but they can be found.
Escoffier call's for 1/3 cup of truffle essence, but he wrote the recipe at a time when true truffles were much easier to find, long before today's chemical options. Many "truffle oils" and "truffle essences" have never seen a truffle, being instead infused with 2,4-dithiapentane.
