Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Jelly Layer 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream together the sugar and softened butter until light and fluffy.
Add the beaten eggs and mix well.
Stir in the milk and vanilla extract.
Gradually add the flour and baking powder, mixing until smooth.
Bake and assemble
Pour the batter into greased layer cake pans.
Bake for 25-30 minutes or until a toothpick comes out clean.
Let the layers cool, then spread fruit jelly between them.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Eggs
- Add structure and richness, helping the batter set and bind.
- Butter
- Adds fat for tenderness and flavor, and helps trap air when creamed with sugar.
- Sugar
- Sweetens the cake and helps create a tender crumb and light texture when creamed.
- Baking powder
- Releases gas during baking so the layers rise and become light.
- Milk
- Adds moisture and helps form a smooth, cohesive batter.
The step that matters
Gradually add the flour and baking powder, mixing until smooth.. Mixing flour into batter develops gluten, so over-mixing can make the cake tough. Stop once the batter is smooth and evenly combined.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, flour):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against sugar, butter, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
