Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Adds sweetness and helps give the filling its smooth, rich body.
- Buttermilk
- Adds moisture and a mild tang that balances the sweetness.
- Flour
- Thickens the filling and gives it a more stable texture.
- Eggs
- Set during baking to firm the filling into a sliceable custard.
