French Custard
Ingredients
Directions
In a flat saucepan, bring the milk to a boil, adding sugar and flavoring to taste.
Beat the egg whites until frothy.
Once the milk is boiling, drop spoonfuls of the beaten egg whites into the milk.
Allow the egg whites to poach in the milk for a few moments before serving.

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 dish and gives it a creamy body.
- Egg whites
- Whipped to a foam, they set into soft, light puffs when poached in hot milk.
The step that matters
Poaching the egg whites. The milk should be boiling when the whites go in, and it should be kept at a gentle simmer or lower while they poach. A hard boil can toughen the whites and make them tear apart, so they stay tender and hold their shape.
“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.
