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 ↓

Ingredients
Directions
Prepare the batter
Peel and grate the potatoes and finely chop the onion. Mix in the eggs, salt, and pepper.
Fry
Heat a griddle or frying pan and add a generous amount of cooking oil.
Drop spoonfuls of the batter onto the hot griddle or pour the mixture in.
Fry until golden on both sides.
Place cooked blynai on paper towels or newspaper briefly to absorb excess grease.
Serve
Serve with a dollop of sour cream and/or applesauce.

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 give it a tender, starchy interior.
- Potato starch
- Binds the grated potato so the pancakes hold together while frying.
- Eggs
- Bind the batter and help set the pancakes as they cook.
- Onion
- Adds savory flavor and aroma to the batter.
The step that matters
Fry until golden on both sides. Grated potato holds a lot of water, so the batter can steam and turn pale or soggy if the oil is not hot enough. Hot oil browns the surface quickly and crisps the outside, while the pancake must be turned to cook evenly through.
Swap the onion
How well each one fits the dish's main ingredients (potato, flour, egg, pepper):
- Chivefits better
- Spinachfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against potato, flour, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
