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 Fritters
Ingredients
Directions
Make the batter
While the potato is warm, mix the butter with it.
Add the sugar, lemon juice and rind, and flour.
Break the eggs over these ingredients and beat until very light.
Fry and serve
Fry in lard, barely deep enough to cover them, in a frying pan.
Serve piled on a platter and sprinkled with sugar.

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
- Potato puree
- Forms the bulk of the fritters and gives them a soft, moist interior.
- Eggs
- Bind the mixture and, when beaten, lighten its texture.
- Butter
- Adds richness and fat, contributing to flavour and tenderness.
- Flour
- Adds body so the mixture holds together while frying.
- Sugar
- Adds sweetness and helps the outside brown in the pan.
The step that matters
Beating the eggs until very light. Beating incorporates air into the eggs, which helps lighten the batter so the fritters stay tender rather than dense. Under-beating leaves a heavier texture.
Swap the potato
How well each one fits the dish's main ingredients (flour, butter, sugar, lemon, egg):
- Arrowrootfits better
- Shallotfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against flour, butter, sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
