Why it works: Banana and raspberry work together. They rank in the top 7% of all ingredient pairs, and cooks put them together in 125 recipes. Both carry ethyl benzoate, which smells fruity, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- Provide a nutty flavor and a crunchy texture that contrasts with the soft custard.
- Stale cake crumbs
- Absorb custard and jam, giving the mixture body and a soft, spoonable structure.
- Boiled custard
- Supplies moisture and richness, binding the crumbs and fruit into a creamy layer.
- Raspberry jam
- Adds sweetness and fruity acidity that cut through the richness of the custard.
- Bananas
- Add soft texture and natural sweetness to the middle layer.
The step that matters
Mixing to a thick mixture. Adding custard gradually until the mixture is thick keeps the crumbs from becoming soggy. Too much liquid makes the base collapse instead of holding its shape when spooned.
Swap the angelica
How well each one fits the dish's main ingredients (walnut, banana, raspberry):
- Cinnamonfits better
- Nutmegfits better
- Peppermintfits better
- Angelicathe original
Fit is the average pairing score against walnut, banana, raspberry. Candidates are from the same food group and used in at least 100 recipes.
