Why it works: Potato and pork are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,668 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Swiss Potato Soup
Ingredients
Directions
In a large pot, combine the sliced potatoes and turnips with 5 pints of water.
Boil for 5 to 6 hours, adding boiling water as needed to maintain the level.
Once the mixture is thick and has a pea soup consistency, stir in butter, pepper, and salt.
If desired, add a small piece of salt pork, a bone, or a bit of lamb or veal, along with a small onion for extra flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down during long boiling to thicken the broth into a creamy body.
- Turnips
- Add body and a mild, slightly peppery flavor as they soften in the broth.
- Butter
- Adds richness and a smooth mouthfeel to the finished soup.
The step that matters
Maintaining the water level during the long boil. Water evaporates over hours of boiling, and if the level drops the vegetables scorch and the soup turns bitter or sticks to the pot. Adding boiling water keeps the simmer steady and the starch gradually releasing into a thick, even consistency.
Swap the turnip
How well each one fits the dish's main ingredients (potato, butter, pepper, pork):
- Capsicumfits better
- Onionfits better
- Asparagusfits better
- Turnipthe original
Fit is the average pairing score against potato, butter, pepper, pork. Candidates are from the same food group and used in at least 100 recipes.
