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 Meringue
Ingredients
Directions
Soak the cake
Arrange the sliced sponge cake in a deep glass dish and pour ½ cup of hot milk over it to soak.
Make the custard
Beat the egg yolks and stir in 4 tablespoons of sugar.
Heat the remaining milk and gradually pour it over the egg mixture while stirring continuously.
Return the mixture to the saucepan and stir until it thickens, then let it cool slightly.
Add the lemon extract and grated lemon rind, then pour over the sponge cake.
Top and serve
Whip the egg whites to stiff peaks, sweeten with 1 tablespoon of sugar, and add a few drops of lemon extract.
Spread the meringue over the cooled cake just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sponge cake
- Forms the soft base that soaks up the hot milk and holds the custard.
- Milk
- Provides the liquid for the soaking and the custard, giving moisture and body.
- Eggs
- Yolks thicken the custard, while whites whip into a foam that forms the meringue topping.
- Sugar
- Sweetens the custard and meringue, and helps the whipped whites hold their shape.
The step that matters
Thickening the custard. Egg yolks set when heated, so the hot milk must be added gradually while stirring constantly. Stirring spreads the heat evenly and keeps the yolks from scrambling into lumps, giving a smooth custard that thickens properly.
