Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Milk
Forms the liquid base of the custard and provides its creamy body.
Egg yolks
Thicken the custard as they set and add richness and colour.
Isinglass
Gelatin-like setting agent that firms the custard as it chills.
Cream
Whipped to add lightness and a soft, airy texture when folded in.
Granulated sugar
Sweetens the custard and helps balance the setting mixture.

The step that matters

Fold the whipped cream into the mixture. Folding gently keeps the air trapped in the whipped cream, so the custard stays light rather than deflating into a dense, heavy texture.
