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 ↓
To Melt Butter
Ingredients
Directions
Use a well-tinned saucepan.
Add water, a pinch of flour, and pieces of butter.
Shake the pan continuously in one direction to prevent the butter from separating.
Once melted, remove from heat.

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
- Butter
- Provides the fat that melts to form the sauce and carries its rich flavour.
- Water
- Adds moisture that helps the butter melt evenly and keeps it from separating.
- Flour
- Helps stabilise the emulsion so the melted butter stays combined.
The step that matters
Shake the pan continuously in one direction. Butter is an emulsion of fat and water. Steady, even agitation keeps the fat and water mixed as it melts, so it does not separate into layers.
