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 ↓
Strawberry Floating Island
Ingredients
Directions
Make the custard
In a saucepan, combine milk, egg yolks, and sugar. Cook over medium heat until smooth.
Remove from heat and let cool. Once cool, add lemon juice for flavor.
Make the meringue
In a separate bowl, beat egg whites until stiff. Gradually add powdered sugar while continuing to beat.
Gently fold in the sweetened juice from the crushed strawberries into the egg white mixture.
Serve
Serve the cooled custard in a glass dish, topped with spoonfuls of the strawberry meringue.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the milk custard as they cook and add richness.
- Egg whites
- Beaten to stiff peaks, they form the airy, light meringue topping.
- Sugar
- Sweetens the custard and helps stabilise the beaten egg whites.
- Milk
- Forms the base of the custard, providing moisture and body.
- Powdered sugar
- Added gradually to the whites, it dissolves easily and helps keep the meringue stable.
- Crushed strawberries
- Their sweetened juice flavours the meringue with fruit acidity and aroma.
The step that matters
Beating the egg whites to stiff peaks. Whites must be beaten without any trace of yolk or fat, and sugar must be added gradually. Fat or undissolved sugar prevents the foam from reaching stiff peaks and makes it collapse or weep.

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