Why it works: Parsley and pepper 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Old fowl
- Provides the main meat and the rich, savoury flavour of the broth.
- Almonds
- Add body and a nutty richness to the soup's texture.
- Cracker crumbs
- Thicken the soup slightly and give it body.
- Raw eggs
- Set when heated, adding body and thickening the bisque.
- Milk
- Adds richness and creaminess, softening the soup's flavour.
The step that matters
Stir in the beaten eggs mixed with hot milk. Eggs thicken when heated, but if the soup is too hot or the eggs are added too quickly they can scramble into curds. Tempering the eggs with hot milk and stirring steadily keeps the bisque smooth.
Swap the almond
How well each one fits the dish's main ingredients (onion, parsley, milk, pepper, egg):
- Chickpeafits better
- Beansfits better
- Walnutfits better
- Almondthe original
Fit is the average pairing score against onion, parsley, milk, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
