Why it works: Mushroom and truffle are a kitchen classic. They rank in the top 2% of all ingredient pairs, and 1,900 recipes mention both. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the sauce
In a stewpan, combine the ham, herbs, mushroom, white wine, stock, and pepper.
Boil until reduced to half its original quantity, then strain through a sieve.
In another saucepan, blend flour and butter, then add a little stock and cook until reduced by half.
Finish and serve
Combine the two sauces and warm in the foie gras, cocks' combs, truffles, mushrooms, and fonds d'artichauts.
Serve alone or as a garnish for fricasseed fowls or wild pheasants.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw ham
- Gives the ragout its savoury, meaty flavour as it simmers into the sauce.
- Flour
- Thickens the second sauce with butter, giving it body.
- Butter
- Enriches the sauce with fat, adding smoothness and rich flavour.
- Foie gras
- Melts into the warm sauce, adding richness and a silky texture.
- Truffles
- Adds a strong earthy aroma that defines the luxurious character of the dish.
- White wine
- Adds acidity and depth as it reduces, balancing the rich sauce.
The step that matters
Reducing the ham and wine mixture by half. Reducing concentrates flavour and thickens the liquid. Stopping too early leaves a thin, watery sauce, while over-reducing can make it salty and sticky once the ham's saltiness concentrates.
