Why it works: Corn and coconut match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 306 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Lemon 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.
Prepare the layers
Preheat the oven to 350°F (175°C).
In a bowl, mix sugar, eggs, sweet milk, baking powder, and flour until smooth.
Beat the egg whites separately and fold them into the batter last.
Divide the batter into four layers and bake until golden.
Make the filling
For the filling, boil 1 cup of sugar and 1 cup of water.
Thicken the mixture with 1 teaspoon of corn starch.
Once cool, add the juice and grated rind of 1 lemon.
Assemble and frost
Sprinkle each layer with coconut before stacking.
Make a soft frosting with the egg white and top the cake with it.
Sprinkle additional coconut on the frosting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Add structure to the batter and lift when beaten whites are folded in.
- Flour
- Forms the structure that holds the cake layers together.
- Baking powder
- Releases gas in the batter so the layers rise and stay light.
- Sugar
- Sweetens the cake and helps the layers brown while baking.
- Corn starch
- Thickens the lemon filling so it sets rather than running.
- Lemon
- Adds acidity and bright lemon flavour to the filling.
The step that matters
Add the lemon juice and rind only once the filling has cooled. Corn starch thickens when heated and sets as it cools; adding acidic lemon juice while the mixture is still hot can thin it and weaken the set, so cooling first keeps the filling thick.
Swap the lemon
