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 Pancakes
Ingredients
Directions
Prepare the batter
Grate the potatoes and place them in a bowl.
Add the salt, beaten eggs, flour, and baking powder to the potatoes. Mix until you have a nice batter.
Fry
Heat butter in a frying pan over medium heat.
Drop spoonfuls of the batter into the pan and fry until golden brown on both sides.

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
- Potatoes
- Form the bulk of the pancake, giving starchy body and a tender, shreddable texture.
- Eggs
- Bind the grated potatoes together and help the pancakes hold their shape.
- Flour
- Thickens the batter so it holds together rather than running in the pan.
- Baking powder
- Releases gas that lightens the batter and helps the pancakes rise a little.
The step that matters
Frying the spoonfuls of batter. Grated potato turns watery and dark if it sits, so the batter should be mixed and fried promptly. The pan must be hot enough that the pancakes brown before the centers stay raw and soggy.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour, butter):
- Chivefits better
- Shallotfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against egg, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
