Why it works: Milk and lemon are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 19,053 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Lemon Trifle
Ingredients
Directions
Make the custard
Heat the milk in a saucepan.
In a bowl, beat the egg yolks and stir in 4 tablespoons of sugar.
Gradually pour the hot milk into the egg mixture, stirring well.
Return the mixture to the saucepan and stir until it begins to thicken.
Add the lemon juice and grated rind, then pour the hot custard over the sliced cake in a deep dish.
If using a glass dish, preheat it by rolling it in hot water.
Place a heavy saucer on the cake to keep it submerged and let it cool.
Top and chill
Once completely cold, whip the egg whites with the remaining tablespoon of sugar, lemon juice, and rind to make a meringue.
Spread the meringue over the cooled trifle 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, providing moisture and a creamy texture when thickened.
- Eggs
- Yolks thicken the custard as they set with heat; whites whip into the meringue topping.
- Sugar
- Sweetens the custard and meringue and helps the whipped egg whites hold their structure.
- Sliced sponge cake
- Soaks up the warm custard to form the trifle's soft, layered base.
- Lemon
- Adds acidity and aroma from the juice and rind to the custard and meringue.
The step that matters
Return the mixture to the saucepan and stir until it begins to thicken. Egg yolks thicken as they heat, but overheating can scramble them into lumps. Stir constantly over gentle heat and stop as soon as the custard coats a spoon.
