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):
