Why it works: Milk and potato are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 3,611 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk and soft, starchy body of the dough.
- Flour
- Gives the dough structure so the balls hold together when fried.
- Eggs
- Bind the mixture and help set the balls during frying.
- Baking powder
- Releases gas that lightens the balls as they cook.
- Milk
- Adds moisture so the dough stays soft and workable.
The step that matters
Frying the balls in boiling lard. Browning comes from Maillard reactions at the surface, while the centre must cook through. If the lard is too cool, the balls absorb fat and turn greasy; if too hot, they darken before the inside is cooked.
Swap the potato
How well each one fits the dish's main ingredients (milk, flour, egg):
- Arrowrootfits better
- Asparagusfits about as well
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
