Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Apple Float
Ingredients
Directions
Make the custard
Combine the yolks of 3 eggs with 1 quart of milk and 1 heaping teaspoon of corn starch to make a soft custard.
Pour the custard into a dish and let it cool.
Make the apple topping
Beat the whites of 3 eggs until stiff.
Grate 4 large tart apples and mix them with the egg whites and 3 tablespoons of sugar.
Alternatively, use 1 pint of baked or stewed apples, 3 egg whites, and 4 tablespoons of powdered sugar.
Beat until the mixture is stiff enough to stand alone.
Assemble
Fill a dish with the cold custard and pile the apple mixture on top.
Flavor with vanilla extract.

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 into a soft custard as they set with heat.
- Egg whites
- Whipped to a stiff foam that gives the apple topping its light, airy structure.
- Corn starch
- Thickens the milk so the custard holds a soft, spoonable body.
- Tart apples
- Add acidity and bulk to the topping, balancing the sweetness of the sugar.
- Sugar
- Sweetens the apple topping and helps the whipped whites hold their shape.
The step that matters
Beat the apple and egg white mixture until stiff. Egg whites must be beaten until they form stiff peaks so the mixture can hold its shape on the custard. Under-beaten whites collapse and weep, while over-beaten whites turn dry and grainy.
Swap the apple
How well each one fits the dish's main ingredients (egg, milk, corn, sugar, vanilla):
- Figfits better
- Coconutfits better
- Blueberryfits better
- Applethe original
Fit is the average pairing score against egg, milk, corn, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
