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):
