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 ↓
Tri-colored 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 batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the white sugar and butter. Add the flour, sweet milk, baking soda, and cream of tartar; mix well.
Fold in the egg whites gently.
Bake the layers
Pour the batter into two thin square cake pans and bake until golden.
For the second layer, use half the quantity of the same ingredients, substituting red sugar sand for white sugar, and bake in one cake pan.
For the third layer, use the same quantity as the first but with the yolks of the eggs, bake in two cake pans.
Assemble and finish
Once baked, spread jelly between the layers, placing the pink cake in the center, the white cakes on each side, and the yellow cakes on top and bottom.
Frost or sprinkle with sugar as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites provide structure when folded in, while yolks add richness and color to the yellow layers.
- Butter
- Creaming with sugar traps air and adds fat for a tender, rich crumb.
- Flour
- Forms the main structure of the cake once the batter is baked.
- Baking soda
- Reacts with the acid in cream of tartar to help the cake rise.
- Cream of tartar
- Acidic ingredient that works with baking soda to lift the batter and stabilize the egg whites.
- Red sugar sand
- Sweetens the pink layer and adds its color to the batter.
The step that matters
Folding in the egg whites gently. Egg whites hold air that gives the cake its lift. Stirring vigorously deflates the foam, leaving layers dense and flat.
