Why it works: Beef and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Brown Soup
Ingredients
Directions
Prepare
Cut the meat from the bone and remove the marrow.
Heat the marrow and butter in a large saucepan until smoking.
Add the meat and bone, browning them along with the diced vegetables.
Simmer
Pour in the cold water and bring to a boil, skimming off any foam.
Add the salt, black pepper, white pepper, and cloves, then reduce heat and simmer for 4 hours.
Strain the liquid and return it to the saucepan.
Thicken and finish
In a bowl, mix the rice flour with Harvey's sauce and mushroom catsup until smooth.
Stir the mixture into the strained liquid and boil for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Provides rich meaty flavour and gelatin that gives the broth body as it simmers.
- Butter
- Browns the meat and vegetables, adding roasted, savoury flavour to the soup base.
- Rice flour
- Thickens the strained liquid so it becomes a smoother, fuller soup.
- Onion
- Browns and sweetens as it cooks, adding depth to the broth.
- Carrot
- Adds natural sweetness and body to the broth as it simmers.
- Celery
- Adds aromatic savoury flavour to the broth.
The step that matters
Browning the meat and marrow. Heating the marrow and butter until smoking and browning the meat creates Maillard browning, which gives the soup its deep colour and roasted flavour. Pale meat yields a flatter broth.
Swap the white pepper

Fit is the average pairing score against beef, butter, rice, flour, mushroom, sauce, pepper. Candidates are from the same food group and used in at least 100 recipes.
