Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide starchy body, so the pudding sets into a soft, smooth, sliceable texture.
- Butter
- Adds fat for richness and a silky, tender mouthfeel.
- Egg yolks
- Enrich the filling and help it set into a custard-like texture when baked.
- Sugar
- Sweetens the pudding and helps create a smooth, fine-textured base.
- Egg whites
- Whipped and folded in, they add lightness and air to the filling.
- Lemon
- Zest and juice add aroma and a bright acidity that balances the sweetness.
The step that matters
Gently fold in the beaten egg whites. Egg whites hold air only when whipped; folding gently preserves that air so the pudding stays light rather than deflating into a dense layer.
