Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the tart fruit base that gives the pudding its acidity and moisture.
- Stale bread or sponge cake
- Forms the absorbent layers that soak up fruit juices and give the pudding its body.
- Egg whites
- Whisked and spread on top, they set and brown to form a light, crisp meringue-like crust.
- White sugar
- Sweetens the dish and helps the egg-white topping brown in the oven.
The step that matters
Whisking the egg whites thoroughly. Egg whites need to be whisked to a full, stiff foam so they hold air and bake into a light topping rather than a dense, runny layer.
