Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Apple Custard
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the custard
In a bowl, mix the stewed apples, butter, cream, beaten eggs, sugar, and nutmeg until well combined.
Pour the mixture into a prepared puff pastry shell.
Bake
Bake in the moderate oven until set and golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a sliceable structure as they cook.
- Stewed apples
- Provide the main body, moisture and fruity flavour of the filling.
- Butter
- Adds richness and fat, giving a smoother, more tender texture.
- Cream
- Adds richness and softness, helping the custard stay silky.
- Sugar
- Sweetens the filling and balances the tartness of the apples.
The step that matters
Baking until just set. Eggs thicken as they heat, so underbaking leaves the custard runny, while overbaking makes the egg proteins tighten and weep or curdle. Pull it out when the centre barely wobbles and the top is golden.
Swap the apple
How well each one fits the dish's main ingredients (butter, cream, egg, sugar, nutmeg):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Applethe original
Fit is the average pairing score against butter, cream, egg, sugar, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
