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 ↓
Cocoanut 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.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the yolks of 6 eggs and add 2 cups of powdered sugar, then mix in ¾ cup of softened butter and 1 cup of milk.
In another bowl, combine 3½ cups of flour and 2 teaspoons of baking powder.
Gradually add the dry ingredients to the wet mixture.
Fold in the beaten whites of 4 eggs.
Bake and ice
Pour the batter into jelly cake pans and bake until golden.
For the icing, beat the whites of 2 eggs and mix with 1 teacup of powdered sugar and the grated coconut.
Spread the icing evenly on the cooled layers of cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and beaten whites add lift and a light, airy structure.
- All-purpose flour
- Provides the starch and gluten network that gives the cake its structure.
- Baking powder
- Releases gas in the batter, helping the layers rise and turn light.
- Butter
- Adds fat for tenderness and rich flavor in the crumb.
- Powdered sugar
- Sweetens the cake and helps give the batter a fine, tender texture.
- Milk
- Adds moisture to the batter and helps hydrate the flour.
The step that matters
Folding in the beaten egg whites. Egg whites hold air only when beaten to soft peaks; overmixing or deflating them while folding makes the layers dense rather than light and airy.
Swap the coconut
How well each one fits the dish's main ingredients (egg, sugar, butter, milk, flour):
- Vanillafits better
- Raisinfits better
- Figfits about as well
- Coconutthe original
Fit is the average pairing score against egg, sugar, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
