Why it works: Milk and apple 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 Cake
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.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, mix the flour, baking powder, and salt.
Rub in the lard until well combined.
Add the sugar, beaten egg, and milk, mixing until the batter is rather thin.
Pour the batter into a well‑greased flat baking tin.
Prepare the filling
Peel, core, and slice the apples, then cook them with a little water until they can be beaten to a pulp.
Sweeten the apple mixture with sugar to taste.
Bake and serve
Once the cake is baked, split it in half and fill the middle with the apple mixture.
Sprinkle fine sugar on top before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the cake as its starches set during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Egg
- Binds the batter and adds structure and richness as it sets.
- Lard
- Rubbed into the flour, it adds fat that tenderises the crumb.
- Apples
- Cooked to a pulp, they add moisture and fruity flavour to the filling.
- Sugar
- Sweetens the batter and filling and adds softness to the crumb.
The step that matters
Keeping the batter thin. The batter is meant to be rather thin. If it is stiffened with too little liquid, the cake can bake dense and dry. Mix only until combined so the flour does not toughen with overworking.
Swap the apple
How well each one fits the dish's main ingredients (flour, sugar, egg, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against flour, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
