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 ↓

Ingredients
Directions
Prepare the batter
Peel and grate the potatoes.
In a bowl, combine grated potatoes, eggs, flour, sugar, and salt. Mix well until combined.
Fry

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 main body of the pancake and, once grated, supply starch that helps hold it together.
- Eggs
- Bind the grated potato together so the pancakes hold their shape while frying.
- Flour
- Absorbs excess moisture from the grated potato and adds body to the batter.
- Sugar
- Adds a little sweetness and helps the surface brown during frying.
- Butter and lard
- Fat for frying that conducts heat and adds flavour and browning to the crust.
The step that matters
Fry slowly over medium heat. Grated potato holds a lot of water and starch. If the heat is too high the outside browns before the inside cooks through, and the pancake can burn or stay raw in the middle. Slow frying lets the interior cook while the surface turns golden.
Swap the potato
How well each one fits the dish's main ingredients (egg, flour, sugar, butter):
- Chivefits better
- Leekfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against egg, flour, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
