Why it works: Potato and egg are a kitchen classic. They rank in the top 29% of all ingredient pairs, and cooks put them together in 4,978 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓

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.

What each ingredient does
- Potatoes
- Provide the starchy bulk that makes up the body of the balls.
- Baking powder
- Releases gas when heated, puffing the balls to make them light inside.
- Eggs
- Bind the grated potato so the mixture holds together when dropped into fat.
The step that matters
Frying in boiling lard. The fat must be hot enough to set the outside quickly. This seals the surface, helps the balls keep their shape, and lets the baking powder lift the interior before the centre becomes greasy and dense.
