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 ↓
Walnut Trifle
Ingredients
Directions
Prepare
Pass the walnuts through a nut mill.
Assemble and serve
Mix the walnuts, cake crumbs, bananas, raspberry jam, and enough custard to form a fairly firm paste.
Place the mixture in a dish and cover with custard.
Scatter some milled walnuts on top and decorate with whole walnuts, angelica, and cherries.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- Provide bulk and a nutty texture that gives the trifle body.
- Stale cake crumbs
- Absorb custard and jam, giving the mixture a firm, paste-like structure.
- Raspberry jam
- Adds sweetness and fruity flavour, and moistens the crumbs.
- Boiled custard
- Binds the mixture into a paste and adds moisture and creamy richness.
The step that matters
Forming the firm paste. Enough custard must be mixed in so the crumbs and walnuts bind into a paste that holds its shape. Too little leaves the mixture dry and crumbly, while too much makes it soggy and loose.
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.
