Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Chicken Broth
Ingredients
Directions
Prepare the chickens
Draw, stuff, and truss the chickens for roasting.
Tie their legs and wings close to their bodies with soft pack-thread.
Place the chickens in a pot with 4 quarts of cold water and a little coarse sea salt.
Boil gently for at least 1 hour.
Check for tenderness with a fork.
If it pierces the breast easily, remove the chickens, butter them well, and keep warm covered.
Make the broth and rice
Take out 1 cup of broth when the chickens are three-quarters done to cook the rice.
Strain the broth after removing the chickens.
Season with pepper and chopped parsley, then return to the heat.
Skim off any scum that rises and boil hard for 15 minutes.
Add ½ cup of rice that has been stewed soft in a little water.
Simmer for 15 minutes.
Thicken and serve
In a separate bowl, stir 1 tablespoon of rice flour into 1 cup of milk.
Bring to a slow boil.
Pour a few spoonfuls of the hot broth into the milk mixture, then return it to the soup and stir well.
In the bottom of a tureen, place the giblets and 1 finely chopped hard-boiled egg.
Pour the broth over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice flour
- Thickens the milk mixture so the soup becomes creamy and lightly body-rich.
- Rice
- Softened in broth, it adds body and a soft, thickened texture to the soup.
- Milk
- Adds richness and creaminess to the soup once thickened with rice flour.
- Eggs
- Beaten eggs are listed in the ingredients but no step states how they are used.
The step that matters
Add the milk mixture gently. Hot broth must be added to the milk-flour mixture a little at a time and stirred well, so the flour disperses evenly and the milk does not curdle or form lumps.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, pepper, rice, milk, flour, egg):
- Turmericfits better
- Cinnamonfits about as well
- Nutmegfits about as well
- Parsleythe original
Fit is the average pairing score against chicken, pepper, rice, milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
