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 that the yolks thicken into a custard.
- Egg yolks
- Thicken the milk and give the custard its set and rich texture.
- Egg whites
- Form a light, airy foam that gives the dish its delicate lift.
- Sugar
- Adds sweetness and balances the richness of the eggs and milk.
The step that matters
Pouring the yolk mixture into the boiling milk. Egg yolks thicken through gentle heat and can scramble and turn grainy if they get too hot too quickly. Adding them to hot milk needs care so the custard sets smooth rather than curdled.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
