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 ↓
Lemon Cake
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 batter
Preheat the oven to 350°F (175°C).
In a bowl, mix the milk, eggs, flour, and baking powder until smooth.
Bake and assemble
Pour the batter into jelly tins and bake until golden.
Once baked, place the cake between the grated apples and lemon mixed with sugar.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and bind the batter, giving the cake its structure and body.
- Flour
- Forms the gluten network that gives the cake its main structure.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Milk
- Adds moisture to the batter so the crumb stays soft.
- Apples
- Add moisture and fruit flavour to the cake layers.
- Lemon
- Adds bright acidity and aroma that balance the sweetness.
The step that matters
Bake until golden. Baking sets the egg and flour structure. Taking the cake out too early can leave the centre wet and sunken, and it may collapse once it cools.
Swap the apple
How well each one fits the dish's main ingredients (milk, egg, flour, lemon, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against milk, egg, flour, lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
