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 Pancake
Ingredients
Directions
Prepare the potatoes
Grate the raw potatoes.
Let them drain in a colander to remove excess juice.
Make the batter
In a bowl, mix the drained potatoes with the egg, salt, nutmeg, and onion.

Spoon the potato mixture into the skillet.
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
- Raw potatoes
- Provide the starchy base that binds and fries up crisp and tender.
- Egg
- Binds the grated potato together so the pancakes hold their shape.
- Onion
- Adds sweetness and aroma as it cooks with the potato.
- Butter and lard
- Fat for frying that promotes browning and a golden crust.
The step that matters
Draining the grated potatoes. Potatoes hold a lot of liquid, and excess water steams the pancakes instead of letting them brown. Draining well helps the mixture crisp and keeps the batter from falling apart.
