This luxurious sauce is not to be confused with stroganoff. The delicate complexity comes from white wine. I used less wine than the recipe called for; I think just a hint of wine is better. Toss it through cooked pasta or serve it with roasted meats. The wine of course can be replaced with water in which case the heavy cream will become dominant. I wouldn't add stock though, it would only muddy the delicate flavour and making it “lighter” would be a shame.
