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 ↓
Lemon 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.
Make the cake batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Add the milk and mix well.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, mixing until smooth.
Beat in the eggs one at a time until fully incorporated.
Bake the layers
Pour the batter into jelly pans and bake for 25-30 minutes or until a toothpick comes out clean.
Make the lemon jelly
For the jelly, combine the white sugar, egg, lemon zest, and butter in a saucepan.
Beat the mixture together and boil for 3 minutes.
Let the jelly cool completely before using.
Assemble
Spread the jelly between the cake layers and frost the top and sides.

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
- Bind the batter and add structure as the cake sets in the oven.
- Butter
- Adds richness and tenderness through fat coating the flour and creaming air into the batter.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
- Sweet milk
- Adds moisture and helps the batter form a smooth, even mixture.
The step that matters
Cool the lemon jelly completely. Hot jelly is runny and will soak into or slide off the cake layers. Cooling lets it thicken and set so it spreads cleanly between the layers.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, egg):

Fit is the average pairing score against sugar, butter, milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
