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 ↓

Make the dough
Bring the sweet milk to a boil.

Add a pinch of salt.
Let the mixture cool, then add the egg.

Serve

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Egg
- Binds the dough so the balls hold their shape during cooking.
- Sweet milk
- Forms the liquid base that the flour thickens into a stiff dough.
- Dry flour
- Thickens the milk and gives the dough body so it can be shaped into balls.
The step that matters
Let the mixture cool before adding the egg. Eggs can scramble or cook unevenly in very hot mixtures, so letting the dough cool first helps the egg blend smoothly and bind the dough evenly.
