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, white pepper, salt, and lemon peel.
Cover with water and stew until the giblets are tender.
Make the soup
Strain the soup.
In a separate pan, melt the butter and stir in the flour until brown.
Pour the strained soup into the pan.
Bring to a boil while stirring.
After 10 minutes, skim the soup.
Strain the soup again.
Finish and serve
Add Madeira, cayenne pepper, 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 or duck giblets
- Provide the main meat and body of the soup as they stew until tender.
- Butter and flour
- Form a browned roux that thickens the soup and adds a toasted, nutty flavour.
- Madeira
- Adds sweetness and rich, deep aroma to the finished soup.
- Onions
- Build savoury depth and sweetness as they cook into the stock.
The step that matters
Browning the flour in the butter. Flour cooked in fat must be stirred until evenly brown; undercooked flour leaves a raw, pasty taste and weak thickening, while over-browning gives bitterness and dark colour.
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.
