Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Gravy Soup
Ingredients
Directions
Prepare
Place the meat at the bottom of a pot and add a piece of butter.
Chop the herbs and roots finely and layer them over the meat.
Cook
Cover the pot tightly and cook over low heat to extract the flavors.
When the gravy is nearly dry, add water to replenish it and remove any fat.
Ensure the ingredients are well proportioned for a balanced taste.
Finish
For white soup, add cream only after removing it from the heat.
If the soup is too thin, mix a little butter with flour to thicken it.

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
- Meat
- Provides the main savory flavor and richness of the broth.
- Butter
- Adds fat and richness, carrying flavor and smoothing the texture.
- Roots
- Contribute sweetness and body to the broth as they cook down.
- Herbs
- Add aromatic flavor that infuses the soup during slow cooking.
- Flour
- Thickens the soup when cooked with butter into a roux.
The step that matters
Cover the pot tightly and cook over low heat. Low, covered heat extracts flavor gradually without boiling off the liquid or scorching the bottom. Too much heat can make the broth cloudy and burnt.
