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 ↓
Velvet Potato Puffs
Ingredients
Directions
Make the potato dough
Pare the potatoes and boil them with salt until done.
Drain most of the water, leaving a little.
Return the potatoes to heat.
Sift in the flour.
Cover and steam for 5 minutes.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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 dough, giving the puffs their soft, fluffy interior.
- Flour
- Absorbs moisture from the mashed potato, helping the puffs hold their shape while frying.
- Goose fat or butter
- Conducts heat for frying and browns the outside of the puffs to a golden crust.
- Onion
- Adds savory flavor that sweetens and deepens as it browns in the fat.
The step that matters
Mash the potatoes until smooth and well salted. Lumps and unevenly mixed flour leave dense or crumbly spots, and salt must be evenly distributed because it seasons the dough throughout rather than just its surface.
Swap the onion
How well each one fits the dish's main ingredients (potato, flour, butter):
- Chivefits better
- Leekfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against potato, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
