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 ↓
Jelly 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.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the egg yolks and mix well.
Stir in the milk, baking powder, flour, and cornstarch until smooth.
In a separate bowl, beat the egg whites until stiff peaks form, then fold into the batter.
Divide the batter evenly among three greased cake pans.
Make the filling
For the filling, combine ½ pint milk, ½ cup sugar, and 2 teaspoons cornstarch in a saucepan.
Beat the egg yolks and stir them into the milk mixture.
Cook over boiling water, stirring constantly, until thickened.
Once cooled, flavor the filling with lemon.
Bake and assemble
Bake for 25-30 minutes or until a toothpick comes out clean.
Spread the jelly or lemon filling between the layers of cake.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Egg whites add lift and structure, while yolks enrich the batter and custard.
- Flour
- Provides the structure that holds the cake layers together.
- Baking powder
- Releases gas in the batter, helping the layers rise as they bake.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps keep it moist and tender.
- Cornstarch
- Thickens the filling and softens the cake crumb.
The step that matters
Cooking the filling over boiling water. Stirring constantly keeps the milk and egg mixture from scorching or forming lumps, and the starch thickens it evenly as it heats.
