Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ingredients
Directions
Make the custard
Place the milk in a pan and set it in a kettle of boiling water.
When the milk boils, add the beaten yolks of the eggs mixed with the sugar and 1 teaspoon of milk.
Stir until thickened to the consistency of cream.
Once cold, add the vanilla and pour into a glass dish.
Top with meringue
Beat the egg whites to stiff froth, then mix in the powdered sugar and lemon essence.
Drop spoonfuls of the egg white mixture onto the custard.
Optionally, lay sliced oranges or pineapple in the bottom of the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard and whites whip into the light, airy topping.
- Milk
- Forms the liquid base of the custard, which sets as it thickens with heat.
- Granulated sugar
- Sweetens the custard and helps stabilise the yolks as they cook.
- Powdered sugar
- Sweetens the egg white meringue and dissolves easily into it.
The step that matters
Stir until thickened to the consistency of cream. Egg yolks thicken the milk gently over heat. If the custard gets too hot or is stirred too little, the yolks can scramble or the custard may stay thin. Heat it slowly over the water bath and stop once it coats a spoon.
Swap the orange
The recipe marks orange as optional. How well each one fits the dish's main ingredients (milk, egg, sugar, vanilla, lemon):

- Orangethe original
Fit is the average pairing score against milk, egg, sugar, vanilla, lemon. Candidates are from the same food group and used in at least 100 recipes.
