Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the milk into a soft custard that sets as it cools.
- Milk
- Forms the liquid base of the custard, adding moisture and richness.
- Stale cake slices
- Absorb the custard and give the trifle its soft, layered body.
- Jelly
- Adds sweetness and fruity flavor between the cake layers.
- Egg whites
- Whipped into a light foam that forms the airy topping.
The step that matters
Make the custard. Egg yolks thicken when heated gently; if the custard gets too hot, it can curdle or scramble instead of becoming smooth and soft.
