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 ↓

Ingredients
Directions
Make the soup base
In a bowl, beat the yolks of three eggs with one cup of milk.
Over low heat, blend in one ounce of flour, stirring until smooth but not too thick.
Gradually add one and a half quarts of boiling chicken broth, stirring well.
Season and finish
Season with pepper, coarse sea salt, and one tablespoon of minced parsley.
Strain the mixture into a serving pot.
Just before serving, stir in one tablespoon each of boiled rice, cooked green peas, sliced carrots, and chopped asparagus.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify and thicken the soup, adding richness and a silky body when gently heated.
- Flour
- Thickens the broth, giving it body so it is not watery.
- Milk
- Adds creaminess and softness, mellowing the flavour of the broth.
- Chicken broth
- Forms the liquid base of the soup and carries its savoury flavour.
The step that matters
Adding the broth to the egg and milk mixture. Egg yolks can scramble if they get too hot or are mixed with hot liquid too quickly. Adding the boiling broth gradually while stirring warms the yolks evenly, keeping the soup smooth rather than curdled.
Swap the peas
How well each one fits the dish's main ingredients (egg, milk, flour, chicken, pepper, parsley, rice):
- Chickpeafits better
- Beansfits better
- Cashew nutfits better
- Peasthe original
Fit is the average pairing score against egg, milk, flour, chicken, pepper, parsley, rice. 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.
