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 and let it boil for 5 minutes.
Fry the bread and serve
Cut the dry bread into small dice and fry in hot lard until brown.
Drain the fried bread and place it in the bottom of a soup tureen.
Pour the soup over the fried bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down when boiled and pureed to give the soup its body and thickness.
- Milk or cream
- Adds richness and smoothness, thinning the puree to a creamy consistency.
- Butter
- Adds fat for richer flavour and a silkier mouthfeel in the finished soup.
- Dry bread
- Fried in lard until brown, it gives a crisp, toasty contrast to the smooth soup.
- Salt pork
- Renders savoury fat and seasoning into the cooking water that flavours the potatoes.
The step that matters
Frying the bread until brown. Bread fries quickly once the surface is hot. Too little heat leaves it greasy and soft, while too much browns the outside before the inside crisps, so it should be fried in hot lard and drained well before it meets the soup.
Swap the celery
How well each one fits the dish's main ingredients (potato, pork, milk, butter, parsley, bread):
- Thymefits better
- Marjoramfits better
- Nutmegfits about as well
- Celerythe original
Fit is the average pairing score against potato, pork, milk, butter, parsley, bread. Candidates are from the same food group and used in at least 100 recipes.
