Why it works: Almond and flour are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Apple Custards
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the apples
Peel and core the apples, then cook them slowly in slightly sweetened water until tender.
Drain the apples and place each one in a large custard cup.
Fill the center of each apple with chopped almonds.
Make and bake the custard
In a bowl, mix the milk, eggs, sugar, flour, and lemon extract until well combined.
Pour the custard mixture into the cups around the apples.
Set the cups in a pan of water and bake at 300°F (150°C) until the custard is set.
Serve
Serve cold with plenty of whipped cream.

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 soft, sliceable structure as they cook.
- Milk
- Forms the liquid base of the custard and gives it a creamy texture.
- Apples
- Cooked until tender, they provide the fruit base that holds the custard.
- Sugar
- Adds sweetness and balances the tartness of the apples.
- Flour
- Thickens the custard slightly and helps it hold its body.
The step that matters
Bake the custard in a water bath until just set. Eggs thicken as they heat, and overbaking causes them to curdle and turn grainy and watery. Setting the cups in a pan of water moderates the heat so the custard cooks gently and stays smooth.
Swap the apple
How well each one fits the dish's main ingredients (almond, milk, egg, sugar, flour, lemon, cream):
