Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Enrich the custard and help it set when baked.
- Egg whites
- Whipped to stiff peaks, they add air and lightness to the filling.
- Melted butter
- Adds fat for richness and a tender, smooth texture.
- Jelly or preserve
- Adds fruity sweetness and acidity, and flavour throughout the filling.
- Sugar
- Sweetens the filling and caramelises on top when sprinkled over the hot custard.
The step that matters
Fold in the egg whites gently. Whites hold air only when whipped to stiff peaks. Folding gently keeps that air in the mixture, so the filling bakes light instead of dense and flat.
