Why it works: Apple and milk are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,104 recipes. Both carry 4-heptenal, which smells creamy, biscuit. The science ↓
Apple Snow
Ingredients
Directions
The book says “a brisk oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Preheat the oven to 350°F (175°C).
Separate the egg whites from the yolks.
Beat the yolks and mix with 3 tablespoons of milk.
In a double boiler, heat the remaining milk until boiling.
Add the beaten yolks and cook for 1 minute.
Stir in ½ cup of sugar and salt.
Remove from heat and let cool.
Pour into a glass serving dish.
Make the apple snow
Bake the whole apples in a covered dish with a little water until tender.
Remove the apples from the oven, peel, and scoop out the pulp, avoiding the cores.
Mix the apple pulp with the remaining sugar, lemon juice, and grated lemon rind.
Beat the egg whites until stiff.
Gradually fold in the cold apple pulp until smooth and white.
Assemble and chill
Pile the apple mixture on top of the custard and chill until thoroughly cold before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the bulk of the pulp that makes the fluffy apple layer.
- Egg whites
- Whipped to stiff peaks, they give the apple layer its light, airy structure.
- Egg yolks
- Thicken the milk into a custard as they cook gently.
- Milk
- Forms the custard base, providing moisture and a creamy texture.
- Sugar
- Sweetens the custard and the apple layer.
- Lemon
- Adds acidity and aroma that brighten the sweet apple pulp.
The step that matters
Folding the cold apple pulp into the egg whites. Folding gently keeps the whipped whites full of air. Overmixing or adding pulp that is still warm can deflate the foam, leaving the topping dense rather than light.
Swap the apple
How well each one fits the dish's main ingredients (sugar, lemon, milk, egg):
- Vanillafits better
- Orangefits better
- Figfits better
- Applethe original
Fit is the average pairing score against sugar, lemon, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
