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

What each ingredient does

Bread
Provides the structure that holds the sandwich together.
Butter
Adds fat and richness to the bread, helping it taste savory and smooth.
Tart apple
Supplies the crisp, juicy filling and its fresh acidity.
Lemon juice
Adds acidity that brightens the apple's flavour and slows its browning.
Sugar
Adds sweetness that balances the tartness of the apple and lemon juice.

The step that matters

Soaking the apple slices in lemon juice mixture. Acid from lemon juice slows enzymatic browning of cut apple, so soaking keeps the slices pale. Soaking for the full time also lets the sugar and acid season the fruit evenly.
