Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the apple filling as it cooks, giving it body and structure.
- Sugar
- Sweetens the syrup and filling, and helps preserve the cake layers.
- Arrack
- Adds aroma and flavor to the sponge or almond layers.
- Rum
- Adds aroma and flavor and moistens the crumb-and-syrup layer.
- Tart apple
- Adds acidity and moisture to the filling, balancing the sweetness.
The step that matters
Boiling the apple filling while stirring. Boiling the egg and grated apple mixture while stirring keeps the egg from scrambling and lets the filling thicken evenly into a spreadable layer.
Swap the apple
The recipe marks apple as optional. How well each one fits the dish's main ingredients (almond, sugar, rum, crab, brandy, lemon, egg):
- Vanillafits better
- Raisinfits better
- Orangefits better
- Applethe original
Fit is the average pairing score against almond, sugar, rum, crab, brandy, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
