The French Périgord is the truffle heart of France. The region is also known for its culinary products, such as Confit de Canard, wines from Bergerac and Monbazillac, Foie Gras and Sauce Périgueux. This sauce is a classic in the French kitchen. Its basis is a white sauce made with shallot, a reduction of white wine, (goose) fat, stock and lots of truffle. The ‘original’ recipe of this truffle sauce can be found in La Bonne Cuisine du Périgord written in 1929 by La Mazille. The sauce works beautifully with Tournedos and Magret de Canard. And since white asparagus love truffles, why not combine them with Sauce Périgueux?
We don’t think a roux-based sauce will go very well with asparagus, so we combined two recipes: the flavors of Sauce Périgueux with the lightness and consistency of Japanese Kimizu.
We enjoyed our asparagus with a glass of Riesling, produced by Bott Geyl in the French Alsace. This fresh, aromatic, dry white wine with a hint of sweetness and high acidity combines very well with the sweetness of the asparagus and the intense, rich flavor of the sauce. The wine supports the dish perfectly.
What You Need
- 6 White Asparagus
- 1 Small Truffle
- For the Sauce
- 1 Shallot
- 1 Glass of Dry White Wine
- 3 Black Peppercorns
- ½ tablespoon Simple White Vinegar
- Two Cubes of Jus de Truffe*
- 2 egg yolks
- White Pepper
What You Do
Chop the shallot, crush the peppercorns coarsely, add to a pan and add a glass of white wine. Leave to simmer for 20 minutes. Add a splash of white vinegar. Leave to simmer for 10 minutes. Add the two cubes of jus de truffe and leave to simmer for another 10 minutes. Pass through a sieve. If all is well you should have 4 tablespoons of liquid. If necessary reduce. Set aside and leave to cool.
Peel the asparagus and steam for 20 minutes, depending on the size. When there is still 10 minutes on the clock, start working on the sauce. Whisk the two egg yolks well, add the 4 tablespoons of liquid, mix and heat in the microwave on 30% power. Start with one interval of 10 seconds, stir, followed by an interval of 5 seconds, stir and continue with intervals of 5 seconds until you have the right consistency. Total time in the microwave will be approximately 60 seconds. Allow to cool for a minute or two. In the meantime grate the truffle. Serve the sauce over the asparagus, add some white pepper and sprinkle the truffle over the sauce and the asparagus.
* Best to buy a can of jus de truffe and freeze the content in an ice cube bag.
