Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Potato Cakes
Ingredients
Directions
Prepare the potatoes
Peel and grate the raw potatoes.
Place the grated potatoes in a sieve to drain off the liquid.
Make the batter
In a bowl, combine the drained potato pulp with the egg, flour, salt, sugar, and grated lemon peel to form a thick batter.
Fry and serve
Heat butter in a pan and fry the batter in small cakes, browning lightly on both sides.
Serve very hot.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Raw potatoes
- Provide the starchy base that forms the body of the cakes.
- Egg
- Binds the grated potato and flour so the batter holds together while frying.
- Flour
- Thickens the batter and helps the cakes hold their shape.
- Butter
- Fries the cakes, adding richness and encouraging light browning on the surface.
The step that matters
Draining the grated potatoes. Excess liquid dilutes the batter and keeps the cakes from binding, so they can fall apart or steam instead of browning. Draining well helps them hold together and crisp in the pan.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour, sugar, lemon, butter):
- Arrowrootfits better
- Shallotfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against egg, flour, sugar, lemon, butter. Candidates are from the same food group and used in at least 100 recipes.
