Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites whipped to stiff peaks give the balls a light, airy structure, while yolks enrich the batter.
- Flour
- Provides the structure that holds the soft balls together as they fry.
- Baking powder
- Releases gas in the batter, making the balls rise and turn puffy in the hot fat.
- Milk
- Hydrates the flour and adds moisture and softness to the batter.
- Sugar
- Adds sweetness and helps the surface take on a delicate brown colour as it fries.
The step that matters
Folding in the egg whites. Whites beaten to stiff peaks trap air that makes the balls puff. Stirring them in vigorously knocks out that air, so the balls turn out dense instead of light.
