Why it works: Egg and milk are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 88,785 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Floating Islands
Ingredients
Directions
Make the custard
Beat the yolks of five eggs and the whites of two until light.
Sweeten with five tablespoons of sugar and add flavoring to taste.
Stir into a quart of scalded milk and cook until thickened.
When cool, pour into a glass dish.
Make and cook the islands
Whip the whites of three remaining eggs to stiff peaks, adding three tablespoons of sugar and a little flavoring.
Pour this froth over a shallow dish of boiling water to cook with steam.
Once cooked, drop spoonfuls of the froth over the custard, spacing them apart.
Garnish each island with a teaspoonful of bright jelly for a pleasing effect.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set and give it richness and colour.
- Milk
- Forms the body of the custard, which thickens when cooked with the yolks.
- Sugar
- Sweetens the custard and stabilises the whipped egg white froth.
- Egg whites
- Whipped to stiff peaks, they form the light, airy floating islands.
The step that matters
Cooking the meringue islands in steam. Egg white froth must be cooked gently over steam, not boiled directly, so it sets soft and airy rather than collapsing or turning rubbery. Spoon the islands once they are firm enough to hold their shape.
