Why it works: Butter and flour 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 ↓
Chocolate 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
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the butter and sugar.
Add the water, flour, eggs, and baking powder; mix until smooth.
Divide the batter in half.
Grate half a cake of German chocolate into one half of the batter.
Bake
In a greased baking pan, alternate spoonfuls of the light and dark batters until all is used.

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 to the crumb as they set.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Butter
- Adds fat for tenderness and rich flavor.
- Sugar
- Sweetens the cake and helps brown the crust.
- Flour
- Provides the main structure once the proteins set in the oven.
- German chocolate
- Adds chocolate flavor to the dark half of the batter.
The step that matters
Alternate spoonfuls of the light and dark batters. Placing the batters in spoonfuls rather than pouring them together keeps the two colors and flavors distinct, creating a marbled pattern. Overmixing them would blend the batters into one uniform color.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
