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, celery, onion, and mace in just enough water to cover them for 45 minutes.
Mash the potatoes and strain them through a colander into 3 pints of boiling milk.
Add butter, salt, and pepper to the mixture and bring the soup to a boil 2 or 3 times.
Serve
Serve in a tureen garnished with grated parsley and whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down when mashed and strained, thickening the soup and giving it body.
- Milk
- Forms the liquid base and adds creaminess and richness to the soup.
- Butter
- Adds fat for a smoother mouthfeel and a rounded, rich flavor.
- Celery
- Adds aromatic flavor to the cooking liquid that carries into the soup.
- Onion
- Adds aromatic savory flavor to the cooking liquid that carries into the soup.
The step that matters
Adding the strained potatoes to boiling milk. Hot milk should be added to the potato mixture while it is boiling so the soup stays hot and smooth. Repeated boiling then heats the soup through, while adding cold milk could cool it and leave it uneven.
Swap the mace
How well each one fits the dish's main ingredients (potato, celery, onion, milk, butter, pepper, parsley):
- Thymefits better
- Dillfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against potato, celery, onion, milk, butter, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
