Why it works: Sorghum and flour 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 ↓
Confederate Black 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
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, mix the molasses and butter until well combined.
Add the beaten eggs and mix thoroughly.
In a separate bowl, combine the flour, baking soda, spices, and ginger.
Gradually add the dry ingredients to the molasses mixture, stirring until smooth.
Fold in the well-floured dried fruit.
Pour the batter into a greased cake pan.
Bake
Bake for about 45-60 minutes or until a toothpick inserted in the center comes out clean.

Flour and butter 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
- Molasses (sorghum)
- Adds sweetness, moisture, and a deep, dark flavor to the cake.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Eggs
- Bind the batter and add structure and richness as they set.
- Baking soda
- Reacts with the acidic molasses to produce gas, helping the cake rise.
- Dried fruit
- Adds chewy texture and concentrated sweetness throughout the cake.
The step that matters
Gradually add the dry ingredients to the molasses mixture. Adding flour in portions and stirring until smooth prevents lumps and overmixing, which can make the cake tough. Overmixing develops gluten and toughens the crumb.
Swap the apple
How well each one fits the dish's main ingredients (molasses, sorghum, flour, butter, egg, ginger):
- Raisinfits better
- Figfits better
- Vanillafits better
- Applethe original
Fit is the average pairing score against molasses, sorghum, flour, butter, egg, ginger. Candidates are from the same food group and used in at least 100 recipes.
