Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare the batter
Set a quart of water on a brisk fire.
Mix the flour with the egg yolks and a little cold water to form a batter.
Cook
When the water is ready to boil, stir in the batter before it boils.
Keep stirring until it thickens.
Remove from heat, add salt, and pour into a basin.
Let it cool until it is warm like fresh milk.

The flavor team
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.

Shared aroma: isobutyraldehyde (malty, green).
Flour and egg barely smell alike, yet cooks put them together in 106,462 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 yolks
- Enrich the batter with fat and emulsifiers, giving a smooth, rich texture as it thickens.
- Wheaten flour
- Starch thickens the water as it heats, turning the liquid into a smooth pap.
The step that matters
Stir in the batter before the water boils. Adding the batter to water that is ready but not yet boiling lets the starch disperse evenly. Added to a rolling boil, the flour can clump and cook unevenly.
