Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Apple Cup Custard
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the apples
Pare and core the apples.
Steam the apples until tender.
Press the apples through a colander while hot.
Make and bake the custard
Add butter, egg yolks, sugar, and milk to the apple puree, and mix well.
Pour the mixture into baking cups.
Bake at 350°F (175°C) for 20 minutes.
Top and serve
Beat the egg whites until stiff, then gradually add sugar and beat again.
Heap the meringue over the top of the baked custards.
Dust with powdered sugar.
Briefly brown in the oven.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the main body and flavor of the custard as a smooth puree.
- Egg yolks
- Enrich and thicken the custard so it sets softly when baked.
- Egg whites
- Whipped into a meringue that gives a light, airy topping.
- Butter
- Adds richness and a smoother, more tender texture to the custard.
- Milk
- Adds moisture and liquid that helps form a creamy custard.
- Sugar
- Sweetens the custard and meringue and helps stabilize the whipped whites.
The step that matters
Beat the egg whites until stiff. Egg whites must be whipped to firm peaks, with sugar added gradually, to hold air and form a stable meringue. Underbeaten whites will deflate and weep on the custard.
Swap the apple
How well each one fits the dish's main ingredients (butter, egg, sugar, milk):
- Vanillafits better
- Figfits better
- Coconutfits about as well
- Applethe original
Fit is the average pairing score against butter, egg, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
