Why it works: Turnip and celery are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,418 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Milk Soup
Ingredients
Directions
Make the soup base
Boil the chopped onions, turnips, and celery in the water until soft enough to be pulped through a colander.
Season the mixture.
Add the cooking water and milk, and bring to a boil.
Stir in the corn starch.
Simmer for five minutes.
Finish and serve
Gradually stir in the butter to prevent oiling.
Serve the soup over the diced fried bread in a tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the creamy body of the soup and adds richness and mild sweetness.
- Corn starch
- Thickens the liquid as it heats, giving the soup body.
- Butter
- Adds fat for richness and a smooth mouthfeel when stirred in gradually.
- Onions
- Break down while boiling to add savory flavor and body to the pulped base.
- Turnips
- Soften and pulp to give the base bulk and a mild earthy sweetness.
The step that matters
Gradually stir in the butter. Adding fat slowly, while the soup is hot and stirred, helps it emulsify into the liquid. Dumping it in at once can separate, leaving a greasy, oiled surface.
Swap the onion
