Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fish Bisque Maigre
Ingredients
Directions
Prepare the fish
Cut the fish into 1‑inch square pieces and place in a pot with the onion, celery, and boiling water.
Cook until the fish is tender, then remove the pieces with a skimmer.
Remove the bones and chop the fish finely.
Make the soup
Strain the liquid left in the pot and return it to the heat with the minced fish, parsley, and cracker crumbs.
Season with salt and pepper, stir to a gentle boil, then add the butter.
Finally, add the scalding hot milk and simmer for one minute.
Serve
Pour the soup over split Boston crackers that have been soaked in hot milk, salted, peppered, and buttered.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the soup and provides its flesh and flavor.
- Cracker crumbs
- Thicken the broth and give the soup body.
- Milk
- Adds richness and a mild sweetness, softening the soup's flavor.
- Butter
- Adds fat and richness, rounding out the flavor of the soup.
- Boston crackers
- Soak up the soup, giving the dish a soft, bread-like base.
The step that matters
Add the scalding hot milk and simmer only one minute. Milk can curdle or scorch if it is overheated or boiled for long. Adding it hot and simmering briefly keeps it smooth and prevents it from separating into the broth.
Swap the onion
How well each one fits the dish's main ingredients (fish, celery, parsley, milk, butter, pepper):
- Carrotfits better

- Capsicumfits better
- Onionthe original
Fit is the average pairing score against fish, celery, parsley, milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
