Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the eggs until very light.
Add the eggs to the buttermilk.
Mix in the cornmeal, melted butter, and salt.
Dissolve the baking soda in 2 tablespoons of boiling water and add to the batter.
Mix thoroughly and pour into a greased baking pan.
Bake
Bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Add structure and richness as they set during baking.
- Buttermilk
- Provides moisture and tang that adds flavor to the cake.
- Cornmeal
- Forms the body of the cake and gives it a grainy texture.
- Baking soda
- Reacts with the acidic buttermilk to produce gas that lifts the batter.
- Butter
- Adds fat for tenderness and rich flavor.
The step that matters
Dissolving the baking soda in boiling water. Baking soda must be fully dissolved and mixed evenly through the batter so it reacts with the acid in the buttermilk and leavens the cake uniformly. Clumps can leave bitter or uneven spots.
