Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Giblet Soup
Ingredients
Directions
Prepare the giblets
Scald and clean the giblets thoroughly, then cut them into pieces.
Put the giblets in a pot with stock (or water and gravy beef), sweet herbs, onions, whole white pepper, salt, and lemon peel.
Cover with water and stew until the giblets are tender, then strain the soup.
Thicken and finish
In a separate pan, melt butter and stir in flour until brown.
Pour the strained soup into the pan, bring to a boil while stirring.
After 10 minutes, skim and strain the soup again.
Add Madeira, cayenne, mushroom ketchup, and lemon juice.
Serve hot with the giblets in the soup.

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 rich flavour of the soup.
- Butter and flour
- Form a browned roux that thickens the soup and adds nutty flavour.
- Madeira
- Adds sweetness and depth of flavour at the end of cooking.
- Mushroom ketchup
- Adds savoury, umami depth to the soup.
- Lemon juice
- Adds acidity that brightens the rich broth.
The step that matters
Browning the flour in butter. Flour cooked in butter must be stirred until evenly browned before the soup is added. Undercooked roux tastes raw and thickens poorly, while over-browned roux turns bitter and dark.
Swap the white pepper
How well each one fits the dish's main ingredients (beef, onion, lemon, butter, flour, pepper, mushroom):
- Thymefits better
- Parsleyfits better
- Marjoramfits better
- White pepperthe original
Fit is the average pairing score against beef, onion, lemon, butter, flour, pepper, mushroom. Candidates are from the same food group and used in at least 100 recipes.
