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 ↓
Potato Soup
Ingredients
Directions
Make the soup
Boil the potatoes with the salt pork and celery until tender.
Pass the mixture through a colander.
Add milk or cream and butter to achieve a thick cream consistency.
Stir in the chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down into the body and thickness of the soup as they cook and are pressed.
- Milk or cream
- Adds richness and a smooth, creamy texture to the soup.
- Butter
- Adds fat for a richer, silkier mouthfeel in the finished soup.
- Dry bread
- Fried in lard, it becomes crisp and browned, contrasting with the smooth soup.
- Lard
- Conducts heat to brown the bread dice and adds savory fat.
- Onions
- Contribute aroma and mild sweetness when cooked in the soup.
The step that matters
Frying the bread dice until brown. The bread must fry in hot lard long enough to brown and crisp, since the Maillard reaction creates flavor and texture. Too little heat leaves it soggy, and too long burns it bitter.
Swap the celery
How well each one fits the dish's main ingredients (potato, pork, milk, butter, parsley, bread, onion):
- Thymefits better
- Garlicfits better
- Marjoramfits about as well
- Celerythe original
Fit is the average pairing score against potato, pork, milk, butter, parsley, bread, onion. Candidates are from the same food group and used in at least 100 recipes.
