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 5 eggs and the whites of 2 eggs until light.
Sweeten with 5 tablespoons of sugar and add flavoring to taste.
Stir into 1 quart of scalded milk and cook until thickened.
Cool and pour into a glass dish.
Make and cook the islands
Whip the whites of 3 remaining eggs to stiff peaks, adding 3 tablespoons of sugar and a little flavoring.
Pour the froth over a shallow dish of boiling water to cook it 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.

Sugar and milk barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
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 cook and give it a rich, smooth body.
- Milk
- Forms the liquid base of the custard that thickens when heated.
- Egg whites
- Whipped to stiff peaks, they create the light, airy structure of the islands.
- Sugar
- Sweetens the custard and stabilizes the whipped whites for a glossy froth.
The step that matters
Cooking the froth over boiling water. The froth must be cooked with steam just until set; if the water is not boiling or the heat is too long or strong, the islands can collapse or toughen. Egg white proteins set with heat, which holds the foam's shape.
