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 ↓
Maple Sauce
Ingredients
Directions
Make the syrup
In a saucepan, combine maple syrup, granulated sugar, and butter.
Boil the mixture until it forms a soft ball when dropped into cold water.
Thicken and finish
In a small bowl, smooth the flour with a little warm water.
Add the flour mixture to the hot water and stir until combined.
Pour the hot water mixture into the syrup mixture and cook until it thickens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Maple syrup
- Provides the main sweet maple flavour and the liquid base of the sauce.
- Granulated sugar
- Adds sweetness and helps the syrup reach the soft ball stage when boiled.
- Butter
- Adds richness and a smooth, glossy mouthfeel to the sauce.
- Flour
- Thickens the sauce as it cooks, giving it body.
The step that matters
Boil to the soft ball stage. Boiling drives off water and concentrates the sugars. Stopping too early leaves the sauce thin, while going too far makes it firm and sticky. The cold water test shows when the sugar concentration is right.
