Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raspberries
- Provide the main fruit flavor and the juicy body of the filling.
- White sugar
- Sweetens the filling and helps draw out and balance the berries' tartness.
- Flour
- Starch that thickens the released berry juices so the filling sets when baked.
- Butter
- Adds fat for richness and a rounder, buttery flavor in the filling.
The step that matters
Add the flour and sugar mixture to the raspberries and stir.. Flour thickens juice only when its starch is spread evenly through the fruit. Stirring thoroughly prevents dry pockets of flour and uneven, lumpy thickening.
