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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides sweetness and body to the sauce as it dissolves in the hot liquid.
- Flour
- Thickens the sauce as it cooks in the boiling water.
- Butter
- Adds richness and a smooth, glossy finish when stirred in off the heat.
- Orange juice
- Adds acidity and bright citrus flavor to balance the sugar.
The step that matters
Stirring in the butter off the heat. Adding the creamed butter after removing the pan from heat lets it blend smoothly without separating or cooking into an oily layer. Flour needs the boiling step to cook out its raw taste and reach full thickness.
