Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fruit juice
- Provides the main liquid and fruity flavour for the sauce.
- Flour
- Thickens the juice mixture into a spoonable sauce as it heats.
- Butter
- Adds richness and a smooth, glossy texture to the sauce.
- Sugar
- Sweetens the juice to taste and balances its tartness.
- Toast
- Gives a crisp, absorbent base that holds the warm fruit sauce.
The step that matters
Stirring the flour and butter into the hot juice. Flour thickens only when heated in liquid and stirred, so stirring keeps it from clumping and lets the sauce thicken evenly.
