Why it works: Butter and flour 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
- Butter
- Adds richness and a smooth, rounded mouthfeel to the sauce.
- Sugar
- Adds sweetness and, creamed with butter, helps give the sauce a light body.
- Flour
- Thickens the sauce as it heats with the boiling water.
- Boiling water
- Liquid base that dissolves the sugar and hydrates the flour to form the sauce.
The step that matters
Pouring in the boiling water. Flour thickens only when its starch is heated in liquid. Adding the boiling water all at once and stirring steadily keeps the flour from clumping, so the sauce turns smooth rather than lumpy.
Swap the pineapple
How well each one fits the dish's main ingredients (butter, sugar, flour):
- Raisinfits better
- Vanillafits better
- Figfits better
- Pineapplethe original
Fit is the average pairing score against butter, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
