Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped as foam lift the mixture, while yolks enrich and help set the custard.
- Flour
- Starch thickens the scalded milk into a smooth base that holds the puff together.
- Butter
- Fat melted into the base adds richness and a tender mouthfeel.
- Milk
- Forms the liquid base that the flour thickens and the eggs set into custard.
- Chopped cooked ham
- Adds savoury flavour and substance to the puff.
The step that matters
Folding in the stiff egg whites. Whites must be folded gently so the air bubbles they hold are not deflated. Those bubbles are what lift the puff in the oven, so overmixing leaves a dense result.
