Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Potato Pancakes
Ingredients
Directions
Prepare the batter
Grate the raw potatoes and let them drain in a colander to remove excess juice.
Combine the drained potatoes with the egg, salt, nutmeg, and onion in a bowl.
Fry
Heat a mixture of butter and lard in a skillet over medium heat.
Spoon the potato mixture into the skillet and fry until golden brown on both sides, ensuring they are not greasy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base that forms the body of the pancakes.
- Egg
- Binds the grated potato so the pancakes hold together while frying.
- Onion
- Adds savoury flavour and moisture to the potato mixture.
- Butter and lard
- Fat for frying that conducts heat and encourages browning on the surface.
The step that matters
Draining the grated potatoes. Grated potato releases water that turns to steam and softens the batter, so excess juice must be removed. Too much moisture stops the pancakes from crisping and makes them fall apart in the pan.
