Why it works: Potato and milk 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 ↓
Fish Cakes
Ingredients
Directions
Prepare
Remove skin and bones from the fish and shred it finely.
Combine the fish and mashed potatoes in a bowl.
Add the beaten eggs, flour, and seasoning.
Mix in just enough milk to form a paste that can be beaten, but avoid making it too thin.
Fry
Drop spoonfuls of the mixture into hot oil and fry until golden brown.

Flour and milk 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
- Eggs
- Bind the mixture together and help the cakes set when fried.
- Mashed potatoes
- Add body and moisture, keeping the cakes tender inside.
- All-purpose flour
- Thickens the mixture slightly so it holds its shape.
- Milk
- Adds moisture to form a workable paste without making it too thin.
The step that matters
Mix in just enough milk. Too much milk makes the paste thin and loose, so the spoonfuls spread and may fall apart in the hot oil. Adding milk gradually until the mixture just holds together gives cakes that keep their shape.
Swap the potato
How well each one fits the dish's main ingredients (fish, egg, flour, milk):
- Asparagusfits about as well
- Potatothe original
- Leekfits about as well
- Chivefits about as well
Fit is the average pairing score against fish, egg, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
