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, silky mouthfeel to the sauce.
- Flour
- Thickens the sauce as it heats, giving it body.
- Sugar
- Adds sweetness and balances the tartness of the cider.
- Cider
- Forms the liquid base and supplies the apple flavor.
The step that matters
Stirring while the cider boils. Flour thickens only when the liquid is hot enough and stirred, so the starch disperses evenly without lumps. Stopping the stirring or pouring the cider in too fast can leave clumps that stay in the finished sauce.
