Recipe Notes

I was at a fancy restaurant in London when I had this sauce again for the first time in ages and ages. The thing is that Sauce Royale is a super creamy sauce made with difficult to acquire ingredients, like truffles, and rich ingredients including butter and cream. The version that I had was so light and tasty that I thought I would take a pass at making my own version.

First off was a trip to the bible of French cookery: the Larousse Gastronomique. The recipe in this amazing encyclopedia of cooking has a ton of butter, flour, and chicken stock cream, along with a healthy dose of black truffles, and sherry.

After a lot of consideration and a bit of trial and error, this approximation of the classic Sauce Royale recipe is surprisingly wonderful. Granted, black truffle oil (you want black truffle and not white truffle because the flavor is a bit more intense) is not inexpensive, but the remaining ingredients are pretty easy to find for most people. It’s best to start with your own, freshly made chicken stock, but that’s not always practical, either. Try to find some good quality frozen chicken stock, with as little salt as possible, for this recipe. Reducing the chicken stock to help intensify the flavor is key.

I prefer to use garbanzo flour rather than wheat flour for this recipe, and not just because I have Celiac disease: Garbanzo flour has a great nutty flavor and is a thickening agent as good as or even better than white flour. That paired with the truffle oil, chicken stock, frothed milk, and a touch of sherry makes a terrific, silky sauce.
