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 ↓
Bohemian Potato Puff
Ingredients
Directions
Prepare the potatoes
Peel, wash, and boil the potatoes until soft enough to mash.
Drain most of the water, leaving a little, and add a handful of salt.
Return the potatoes to the stove and sift in the flour, covering closely for 5 minutes.
Mash the potatoes until smooth and free of lumps.
Fry the puffs
In a skillet, heat the goose fat and finely chop the onion, cooking until light brown.
Dip a tablespoon in the hot fat, scoop a spoonful of potato dough, and place it in the skillet.
Repeat until all the dough is used, dipping the spoon in fat each time.
Let the puffs brown slightly.

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 dough, becoming soft and fluffy when mashed.
- All-purpose flour
- Absorbs moisture from the potatoes and helps the dough hold its shape.
- Goose fat
- Carries flavor and gives the puffs a golden, crisp browned surface when fried.
- Onion
- Adds savory flavor to the fat as it cooks until light brown.
The step that matters
Mashing until smooth and free of lumps. Lumps of flour or unmashed potato leave pockets in the dough, so the puffs may brown unevenly or hold together poorly in the hot fat.

Fit is the average pairing score against potato, flour. Candidates are from the same food group and used in at least 100 recipes.
