Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Isinglass
- Sets the custard into a firm, sliceable form as it chills.
- Egg yolks
- Thicken the custard and add richness as their proteins set with gentle heat.
- New milk
- Forms the liquid base, giving the custard its creamy body and moisture.
- Loaf sugar
- Adds sweetness and balances the richness of the yolks and milk.
The step that matters
Pouring the hot milk into the egg mixture. Adding hot milk too fast, without constant stirring, can scramble the egg yolks into lumps. Stirring as the milk goes in gently warms the yolks so they thicken evenly into a smooth custard.
