Why it works: Flour and sorghum share more aroma than cooks usually use. They rank in the top 5% of all ingredient pairs, and cooks put them together in 99 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Marble 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batters
Preheat the oven to 350°F (175°C).
In a bowl, beat the egg whites until stiff.
In another bowl, cream together the butter and sugar. Add the milk, flour, baking powder, and flavoring to the butter mixture, mixing well.
In a separate bowl, combine the egg yolks, butter, sorghum molasses, milk, flour, baking powder, and mixed spices.
Marble and bake
Layer the light and dark mixtures in a greased cake pan.
Swirl with a knife to create a marbled effect.
Bake for 30-40 minutes or until a toothpick comes out clean.

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
- Egg whites
- Whipped until stiff to trap air, giving the cake a light, airy crumb.
- Butter
- Creamed with sugar to add richness and a tender texture.
- Sugar
- Creamed with butter to add sweetness and help hold air in the batter.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking powder
- Releases gas during baking so the cake rises.
- Sorghum molasses
- Adds dark color, moisture and a deep sweet flavor to the dark batter.
The step that matters
Swirling the batters. Swirling too much blends the light and dark batters into a uniform color instead of distinct marbling. Use only a few gentle passes with a knife so the two batters stay separate in the pan.
