Why it works: Potato and cream are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 2,481 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓
Potato Pancakes
Ingredients
Directions
Prepare the potatoes
Let the grated potatoes stand for several minutes. Drain off the water and set it aside until the starch settles. Pour off the water and add the starch back to the potatoes.
Make the batter
Beat the eggs thoroughly and mix them with the cream and potatoes. Add salt to taste.
Fry
Fry in plenty of coconut or lard until crisp and brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: (e)-2-octenal (fatty, green).
Egg and cream barely smell alike, yet cooks put them together in 42,166 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 and release starch that helps them crisp when fried.
- Eggs
- Bind the grated potatoes together so the pancakes hold their shape.
- Sour cream
- Adds moisture and a tangy richness to the batter.
- Coconut or lard
- Conducts heat around the pancakes, browning and crisping their surface.
The step that matters
Fry in plenty of fat until crisp and brown. Enough fat surrounds the pancakes so heat transfers evenly and the surface browns and crisps. Too little fat leaves them steaming and pale, and they can stick or turn greasy in uneven patches.
Swap the potato
How well each one fits the dish's main ingredients (egg, cream):
- Spinachfits better
- Asparagusfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against egg, cream. Candidates are from the same food group and used in at least 100 recipes.
