Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Johnny-cake, No. 3
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 400°F (200°C).
Cream the butter and sugar together until smooth.
Beat the egg white until stiff and set aside.
Mix the egg yolk with the creamed butter and sugar.
Sift the flour with the baking powder and salt, then add to the mixture.
Gradually stir in part of the milk, then sift in the Indian meal.
Mix thoroughly, then stir in the remaining milk.
Fold in the beaten egg white gently.
Bake
Pour the batter into a buttered gingerbread pan and bake for 30-35 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- The yolk enriches the batter and the whipped white adds lift and a lighter crumb.
- Indian meal
- Cornmeal gives the cake its coarse, slightly grainy texture and corn flavour.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Milk
- Supplies the liquid that hydrates the flour and meal to form the batter.
The step that matters
Fold in the beaten egg white gently. Beaten egg white holds air bubbles that help the cake rise. Stirring vigorously knocks that air out, leaving a denser cake.
