Why it works: Mushroom and shallot are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,982 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Brown Sauces
Ingredients
Directions
Prepare the vegetables
Fry the chopped mushrooms, carrot, onion, and shallot in 1 tablespoon of butter until browned, but not burnt.
Drain off the butter.
Make the sauce
In a copper saucepan, melt 2 ounces of butter and stir in 2 ounces of flour over heat until pale brown.
Add 1 pint of stock, the fried vegetables, and ½ cup of tomato sauce.
Simmer gently for 30 minutes with the cover off.
Strain the sauce through a fine sieve.
For Chateaubriand, add ⅓ cup of sherry and omit the stock.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Adds earthy flavour and savoury depth as they brown in the butter.
- Flour
- Thickens the sauce when cooked with butter into a roux.
- Butter
- Carries the frying and forms the fat base of the roux.
- Tomato sauce
- Adds acidity, colour and savoury sweetness to the sauce.
- Stock
- Provides the liquid that the roux thickens into sauce.
The step that matters
Cook the roux until pale brown. Cooking flour in fat until pale brown removes raw starch taste and helps it thicken smoothly. Stirring over heat keeps it from scorching and turning bitter.
