Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the body of the custard, and its proteins set into a soft gel once rennet is added.
- Prepared rennet
- Enzyme that curdles the milk proteins so the custard sets into a delicate, spoonable gel.
- Sugar
- Adds sweetness and balances the mild flavour of the milk.
- Vanilla extract
- Adds aroma that rounds out the flavour of the milk.
The step that matters
Stir in the prepared rennet thoroughly. Rennet must be evenly distributed through the milk so that it coagulates the proteins uniformly. Unmixed pockets can set unevenly, leaving soft spots or a grainy texture in the finished custard.
