Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Marble Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Weigh the flour and sugar to match the weight of 3 eggs.
Weigh the butter to match the weight of 2 eggs.
Cream the butter and sugar together until light and fluffy.
Add a little flour and an egg alternately to the mixture.
Finally, mix in the baking powder.
Marble and bake
Divide the batter into three parts: add chocolate to one, cochineal to another, and leave the last plain.
Layer the batters in a prepared cake pan.
Bake in a moderate oven at 350°F (175°C) for 30 to 45 minutes.

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 and richness as the cake sets.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Granulated sugar
- Sweetens the cake and helps create a tender, lighter crumb when creamed with butter.
- Unsalted butter
- Adds fat for tenderness and flavor, and traps air when creamed with sugar.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
The step that matters
Cream the butter and sugar until light and fluffy. Beating softened butter with sugar traps air in the fat, which expands in the oven and helps give the cake a light, even crumb. Underbeaten batter bakes denser.
