Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Soaks up liquid and gives the dessert its soft, layered structure.
- Bananas (in the method)
- Add moisture and natural sweetness as they soften during baking.
- Butter
- Adds richness and helps the bread brown lightly in the pan.
- Sugar
- Adds sweetness and helps the top brown as it bakes.
- Lemon juice
- Adds acidity that brightens the sweet bananas and sugar.
The step that matters
Bake covered until heated through. Covering the dish traps steam, which keeps the bread and bananas moist while the layers heat through evenly.
