Lemon Trifle

Ingredients

Directions

Make the custard

  1. Heat the milk in a saucepan.

  2. In a bowl, beat the egg yolks and stir in 4 tablespoons of sugar.

  3. Gradually pour the hot milk into the egg mixture, stirring well.

  4. Return the mixture to the saucepan and stir until it begins to thicken.

Assemble and cool

  1. If using a glass dish, preheat it by rolling it in hot water.

  2. Pour the hot custard over the sliced sponge cake in a deep dish.

  3. Place a heavy saucer on the cake to keep it submerged and let it cool.

Top and chill

  1. Once cold, whip the egg whites and mix in the remaining tablespoon of sugar, lemon juice, and lemon rind.

  2. Spread the meringue over the cooled cake and refrigerate until ready to serve.

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, giving it a smooth, creamy texture when thickened.
Eggs
Yolks thicken the custard and whites whip into the meringue topping for structure.
Sugar
Sweetens the custard and meringue and helps stabilize the whipped egg whites.
Lemon
Provides the juice and rind that give the custard and meringue their bright, citrus flavor.
Sponge cake
Soaks up the warm custard to form the trifle's soft, moist base layer.

The step that matters

Thickening the custard. Stir the custard over gentle heat only until it coats a spoon. Egg proteins set around 175°F, so overheating can curdle the eggs and leave the custard grainy.
