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
Boil the minced onions, turnip, and celery in the stock or water until tender.
Rub the cooked vegetables through a sieve and add them back to the liquid.
In a separate bowl, mix the flour with a little milk or water until smooth.
Add the flour mixture to the vegetable liquid and stir well.
Pour in the milk and bring to a boil, seasoning with salt, pepper, and sugar if desired.
Serve
Serve hot with fried bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Break down into the sweet, savoury base that gives the soup its body and flavour.
- Turnip
- Adds bulk and mild sweetness, and thickens the soup once rubbed through a sieve.
- French potato flour
- Thickens the liquid when stirred in, giving the soup a smooth, body-rich texture.
- Milk
- Adds richness and a creamy texture to the finished soup.
The step that matters
Adding the flour mixture. Flour mixed with a little cold liquid first stays smooth; added directly to hot liquid it clumps. Stirring well while it is added lets the starch hydrate and thicken evenly.
