Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Giblet Soup
Ingredients
Directions
Prepare the giblets
Wash the giblets well, cut them into small dice, and fry in 1 oz. of butter until browned.
Add the stock, onion, and herbs. Simmer gently for about 1.5 hours until the giblets are tender.
Remove the giblets and strain the stock.
Make the soup
Melt the remaining 1 oz. of butter in a saucepan, stir in the rice flour, and cook until browned.
Add the strained stock, pepper, salt, and mushroom ketchup. Cook for 5 minutes after boiling.
Skim the soup well, then add the giblets back in. Bring to a boil again and serve with toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Goose giblets
- Provide the main meat and body of the soup as they become tender in the stock.
- Rice flour
- Thickens the butter and stock mixture into a smooth, lightly body-rich soup.
- Butter
- Fat that browns the giblets and adds richness and flavor to the base.
- Ham
- Adds savory, salty depth and aroma to the soup.
- Mushroom ketchup
- Adds concentrated savory umami flavor to the stock.
The step that matters
Browning the rice flour in butter. Cooking the flour in butter forms a roux; cooking it until browned develops nutty flavor and color, while stirring prevents lumps when the stock is added.
Swap the onion
How well each one fits the dish's main ingredients (butter, ham, rice, flour, mushroom, ketchup, pepper):
- Shallotfits better
- Capsicumfits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against butter, ham, rice, flour, mushroom, ketchup, pepper. Candidates are from the same food group and used in at least 100 recipes.
