Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Truffles: Provide the dominant earthy aroma that defines the sauce.
Shallots: Add a mild sweetness and aromatic base as they soften in the stock.
Ham: Adds savory, meaty depth to the sauce.
Stock: Forms the liquid base and carries the flavors during simmering.
Béchamel sauce: Adds body and creaminess, thickening the sauce.
Lemon juice: Adds acidity that brightens the rich flavors.

The step that matters

Boiling after adding béchamel. Boiling for only about 1 minute is enough to heat the sauce through. Boiling longer can make a cream or béchamel-based sauce thicken too much, scorch on the bottom, or split. If the color fades, the record suggests adding a little cream.
