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 Custard Pudding
Ingredients
Directions
Make the apple base
Cook the apples with a little sugar, lemon rind, and juice until soft.
Pass the cooked apples through a sieve and stir in the butter and one egg.
Pour the mixture into a buttered pie dish dusted with ratafia crumbs.
Bake and serve
Beat the remaining eggs with the milk and half the cream, sweeten to taste, and pour over the apple mixture.
Bake slowly until just set.
Warm the remaining cream and pour over the pudding 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 main body and fruity flavour of the pudding once cooked and sieved.
- Eggs
- Set the custard as they cook, giving the pudding its structure and a creamy texture.
- Milk
- Forms the liquid base of the custard, adding moisture and softness to the set pudding.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the apple mixture.
- Sugar
- Sweetens the apples and custard and balances the tartness of the lemon.
- Cream
- Adds richness and a smooth texture to the custard and the final topping.
The step that matters
Bake slowly until just set. Egg custards turn grainy and watery if overbaked or heated too fast, because the proteins tighten and squeeze out liquid. Stopping once the centre just wobbles keeps the texture smooth.
