Why it works: Cream and potato 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 batter
Grate the raw potatoes to make about 1 quart of batter.
In a bowl, combine the grated potatoes, eggs, sour cream, baking soda, and salt. Mix well until all ingredients are combined.
Cook and serve
Cook the mixture in a hot skillet until golden brown on both sides.
Serve warm.

The flavor team
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
- Eggs
- Bind the grated potatoes together and add structure to the pancakes.
- Raw potatoes
- Form the body of the pancake, with starch that helps it hold together when cooked.
- Sour cream
- Adds moisture and a mild tang to the batter.
- Baking soda
- Reacts with the batter's acidity to lighten the texture and aid browning.
The step that matters
Cook in a hot skillet until golden on both sides. If the skillet is not hot enough, the grated potatoes release moisture and steam instead of browning, leaving pancakes soggy and pale. A hot pan sets the outside quickly and builds the golden crust.
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.
