Ingredients

Directions

Make the custard

  1. Beat the yolks of the eggs with the powdered sugar until very light.

  2. Heat the milk in a saucepan until it boils, then gradually add it to the beaten eggs.

  3. Set the mixture over low heat, stirring constantly until thickened, but do not let it boil.

  4. Remove from heat, stir for a few minutes, and add the vanilla.

  5. Let the custard cool completely, then pour it into a deep glass dish.

Top and serve

  1. Beat the egg whites with the powdered sugar until stiff, then spread over the custard.

  2. Brown the top with a salamander or broiler, then serve.

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

What each ingredient does

Egg yolks
Thicken the custard as they set with gentle heat, giving it a rich body.
Egg whites
Whip into a stiff foam that forms the topping, which browns under the broiler.
Powdered white sugar
Dissolves easily into the yolks and whites, sweetening the custard and helping the meringue hold its shape.
Milk
Forms the liquid base of the custard, which thickens when the egg proteins set.

The step that matters

Thicken the custard over low heat without boiling. Egg yolks set between about 160 and 180°F and curdle or turn grainy if overheated. Stirring constantly over low heat spreads the heat evenly, so the custard thickens smoothly.
