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 ↓
Floating Island
Ingredients
Directions
Make the islands
Beat the egg whites until stiff.
Gradually add 2 tablespoons of sugar to the egg whites, continuing to beat until frothy.
In a saucepan, bring 1 quart of milk to a boil.
Drop spoonfuls of the beaten egg whites into the boiling milk, being careful not to overcrowd.
Once cooked, remove the egg whites and place them on a platter.
Make the custard
In the same boiling milk, add the beaten egg yolks.
Dissolve 1 tablespoon of cornstarch in a little cold milk and add it to the boiling milk.
Add sugar to taste to the mixture.
Flavor the mixture with lemon, orange, or vanilla.
Assemble and serve
Once cooled, pour the mixture into a dish.
Gently place the egg white islands on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a foam that cooks into light, soft islands with a delicate structure.
- Egg yolks
- Thicken the warm milk into a silky custard as they set with gentle heat.
- Milk
- Forms the base of the custard and poaches the egg white islands.
- Cornstarch
- Thickens the custard so it holds a smooth, spoonable body as it cools.
- Sugar
- Sweetens the custard and helps stabilize the whipped egg whites.
The step that matters
Drop the egg whites into gently simmering milk, not overcrowded. Crowding the pan lowers the milk temperature and makes the islands stick together or cook unevenly. Keeping the milk at a gentle boil and cooking in small batches lets each spoonful set firm and hold its shape.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, milk):
- Vanillafits better

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