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 ↓

Ingredients
Directions
Prepare the soup
Lift out the giblets with a skimmer or spoon into a tureen and keep covered by the fire.
Melt the butter in a clean saucepan, stir in enough flour to make a paste.
Gradually pour in a ladleful of giblet liquor, stirring continuously, then add the rest and boil for 10 minutes.
Skim and strain the soup through a fine sieve into a bowl.
Finish and serve
Return the soup to the saucepan, add Port wine, mushroom catsup, and salt.
Bring to a boil, add the giblets to heat, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the flavour and helps form the flour paste that thickens the soup.
- Flour
- Thickens the giblet liquor into a smooth, lightly body-rich soup.
- Giblet liquor
- Provides the main meaty stock base of the soup.
- Port wine
- Adds sweetness and depth of flavour to the soup.
- Mushroom catsup
- Adds savoury, umami depth to the soup.
The step that matters
Gradually pour in the giblet liquor while stirring. Adding liquid slowly to the butter and flour roux while stirring constantly keeps it smooth; dumping it in at once forms lumps that are hard to remove.
Swap the orange
How well each one fits the dish's main ingredients (butter, flour, port wine, mushroom, sugar):
- Figfits better
- Vanillafits better
- Plumfits better
- Orangethe original
Fit is the average pairing score against butter, flour, port wine, mushroom, sugar. Candidates are from the same food group and used in at least 100 recipes.
