Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare the paste
In a bowl, rub together the browned flour, butter, and salt to form a smooth paste.
Blend the paste with the warm water until smooth.
Make the soup and serve
Slowly pour the mixture into the boiling water while stirring continuously to prevent lumps.
Cut the dry toast into small squares and place them in a bowl.
Pour the soup over the toast and serve.

Shared aroma: isobutyraldehyde (malty, green).
Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Browned flour
- Provides a toasty, nutty flavour and thickens the soup as it is stirred into the water.
- Butter
- Combines with the flour to form a smooth paste and adds richness to the broth.
- Dry toast
- Soaks up the hot soup and gives the dish its bread-based body.
The step that matters
Pouring the paste into the boiling water. Adding the paste slowly while stirring keeps flour from clumping. Starch granules disperse evenly and hydrate as the mixture heats, giving a smooth, thickened soup instead of lumps.
