Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 8,053 recipes mention both. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Giblet Soup
Ingredients
Directions
Make the base
In a stewpan, heat ½ cup of butter over medium heat.
Add the sliced onion, then the minced carrot and turnip; cook until tender and lightly browned.
Add the giblets.
Stir in 1 tablespoon of flour, stirring often to prevent burning.
Cut up the giblets and add them to a soup kettle with the vegetables.
Simmer and strain
Stir in 1 tablespoon of coarse sea salt, 1 teaspoon of pepper, and 3 quarts of water or stock.
Let the mixture simmer slowly for at least 3 hours, then strain it.
Finish and serve
Mash the livers with 1 tablespoon of melted butter and 1 tablespoon of browned flour.
Squeeze the juice of 1 small lemon into the liver mixture and add it to the soup.
In a tureen, place the yolks of 3 hard-boiled eggs cut into 6 pieces and pour the soup over them; serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Giblets
- Provide the main meat and rich flavour that give the soup its body.
- Butter
- Carries the cooking of the vegetables and adds richness to the soup.
- Flour
- Thickens the soup slightly as it cooks in the butter and vegetables.
- Onion
- Builds sweet, savoury depth as it softens and browns in the butter.
- Lemon juice
- Adds acidity that brightens the rich, long-simmered flavour.
- Hard-boiled eggs
- Add soft, creamy texture to the soup when served.
The step that matters
Stirring the flour into the butter. Flour must be cooked briefly with the fat and stirred often; otherwise it can scorch and taste raw or burnt, and it will not thicken the soup evenly.

Fit is the average pairing score against chicken, carrot, turnip, parsley, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
