Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sugar
Provides sweetness and, once boiled with the vinegar, a syrupy body to the filling.
Vinegar
Supplies the sharp, acidic flavour that defines the pie.
Flour
Thickens the filling so it sets rather than running.
Egg
Adds structure and helps the filling set as it bakes.
Rolled cracker
Absorbs liquid and adds body, helping the filling thicken.
Butter
Adds fat for richness and a smoother, softer texture.

The step that matters

Cool the boiled sugar and vinegar before adding the egg. Hot liquid can scramble the egg instead of blending it smoothly. Cooling first lets the egg incorporate evenly so the filling sets with a uniform texture.
