Why it works: Mushroom and thyme are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,557 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓

Ingredients
Directions
Make the stock
Combine thyme, bay leaves, and ½ pint of water in a stewpan.
Heat over high heat, stirring occasionally until a clear glaze forms on the bottom.
Add 10 quarts of stock or 9 quarts of water and 3 ounces of coarse sea salt, and bring to a boil.
Reduce heat and simmer for 2.5 hours, skimming occasionally.
Strain the mixture through a fine cloth into a basin.
Make the sauce
Melt 1 pound of butter over low heat.
Stir in 1.5 pounds of flour and cook for 10 minutes without browning.
Remove from heat and stir until half cold.
Gradually add the strained stock while stirring quickly.
Return to high heat, stirring continuously, and boil for 30 minutes.
Add 2 tablespoons of chopped mushrooms and 1 quart of boiling milk.
Boil for an additional 10 minutes.
Strain and cool
Strain through a tammie into a basin.
Stir occasionally until cold.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as its starch swells in the hot liquid, giving body.
- Butter
- Carries the flour into a roux and adds richness and a smooth mouthfeel.
- Stock
- Forms the savoury liquid base that the sauce is built on.
- Milk
- Adds creaminess and softens the flavour of the sauce.
The step that matters
Cooking the roux without browning. Cooking the flour in butter for 10 minutes drives off its raw taste and lets it thicken fully. Browning would change the colour and flavour, so keep the heat gentle. Adding the stock gradually while stirring quickly prevents lumps.
Swap the thyme
How well each one fits the dish's main ingredients (egg, milk, mushroom, butter, flour):
- Nutmegfits better
- Cinnamonfits about as well
- Capersfits about as well
- Thymethe original
Fit is the average pairing score against egg, milk, mushroom, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
