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 ↓
Oyster Bisque
Ingredients
Directions
Prepare the oysters
Chop the oysters.
In a pot, combine the oyster liquor, water, parsley, onion, bay leaf, celery, and salt; simmer for 30 minutes.
Mash the oysters through a colander and set aside.
Make the bisque
In a separate pan, melt the butter and stir in the flour until smooth.
Add the heated milk and cream to the butter and flour mixture, stirring well.
Combine the oyster mixture with the milk mixture and let simmer for 10 minutes.
Add the egg yolks and cook for 1 minute without boiling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and texture of the bisque once mashed into the base.
- Butter and flour
- Form a roux that thickens the milk and cream into a smooth body.
- Milk and cream
- Supply richness and a silky, body-building liquid for the bisque.
- Egg yolks
- Enrich and thicken the bisque when gently cooked without boiling.
The step that matters
Add the egg yolks without boiling. Egg yolks thicken by gentle heat. If the bisque boils after they go in, the yolks can scramble, leaving a grainy texture instead of a smooth, creamy one.
Swap the onion
How well each one fits the dish's main ingredients (parsley, milk, cream, oyster, pepper, egg, butter):
- Potatofits better
- Asparagusfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against parsley, milk, cream, oyster, pepper, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
