Why it works: Turnip and pepper are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 5,252 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Common Turnip Soup
Ingredients
Directions
Prepare the turnips
Wash, wipe, and peel the turnips, then weigh them.
Cut the turnips into slices about ¼ inch thick.
Stew the turnips

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Form the body of the soup and, once cooked and strained, give it its bulk and texture.
- Butter
- Gently cooks the turnips in fat and adds richness to the finished soup.
- Soup
- Liquid that cooks the turnips and carries their flavour into the final soup.
The step that matters
Stew gently without browning. Cooking the turnips over low heat in butter softens them while keeping them pale. Browning would change the flavour and colour of a soup meant to taste mild and clean.
Swap the turnip
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits better
- Turnipthe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
