Make the filling
In a pot, combine 1 pint of water, 1 tablespoon of butter, and 1 tablespoon of vinegar.
In a separate bowl, mix flour with ¼ pint of water to create a thick paste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the liquid as its starch swells and sets when heated with water.
- Butter
- Adds fat for richness and a smoother, rounded mouthfeel.
- Vinegar
- Provides the sharp acidity that gives the filling its tangy character.
- Sugar
- Adds sweetness that balances the tartness of the vinegar.
The step that matters
Cooking the flour mixture until thickened. Flour must be mixed smoothly into a paste first and cooked long enough for its starch to swell and thicken. Undercooking leaves a thin, starchy filling that will not set properly when cooled.
