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 eggs with five tablespoons of sugar and flavor to taste.
Stir the mixture into a quart of scalded milk and cook until it thickens.
Once cool, pour the custard into a glass dish.
Make the islands and serve
Whip the remaining three egg whites to a stiff froth, adding three tablespoons of sugar and a little flavoring.
Pour the froth over a shallow dish of boiling water to cook it with steam.
Drop spoonfuls of the froth over the custard, spacing them apart to form 'little white islands.'
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 and give it richness and a yellow color when cooked.
- Milk
- Forms the base of the custard, which thickens as it cooks.
- Egg whites
- Whipped into a stiff froth that holds its shape as the islands.
- Sugar
- Sweetens the custard and helps stabilize the whipped egg white froth.
The step that matters
Cooking the froth over steam. The whipped whites must be set by gentle steam, not boiling water splashing on them. Stiff, well-whipped whites hold their shape and cook through, while overheating can make them weep or collapse.
