Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the moist, tender body of the filling as they soften when steamed.
- Sugar
- Sweetens the filling and softens the apples as they steam.
- Melted butter
- Adds fat that coats the dough, helping it brown and stay tender while rolling.
- Grated nuts
- Add texture and a rich, nutty flavor to the filling.
The step that matters
Roll the dough together, constantly sprinkling with melted butter.. Butter brushed between the layers keeps the thin dough pliable so it does not tear, and its fat helps the layers separate and brown in the oven.
Swap the nuts
How well each one fits the dish's main ingredients (apple, sugar, bread, currant, butter):
- Chestnutfits better
- Almondfits better
- Cocoafits better
- Nutsthe original
Fit is the average pairing score against apple, sugar, bread, currant, butter. Candidates are from the same food group and used in at least 100 recipes.
