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 ↓

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
Preheat the oven to 400°F (200°C).
Make the batter
In a bowl, mix the egg, milk, sugar, and molasses, then add the butter or drippings and stir until combined.
In another bowl, combine the cornmeal, flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture to form a light batter.
Bake
Spread the batter onto a large pan.
Bake in the preheated oven until golden brown.

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
- Binds the batter and adds structure as it sets in the oven.
- Milk
- Supplies liquid that hydrates the cornmeal and flour into a batter.
- Butter or beef drippings
- Adds fat for moistness and tenderness in the crumb.
- Cornmeal
- Gives the cake its coarse, grainy texture and corn flavor.
- All-purpose flour
- Provides gluten-based structure so the cake holds together.
- Baking powder
- Releases gas during baking so the batter rises and lightens.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding dry ingredients slowly and mixing only until combined keeps the batter light. Overmixing develops gluten in the flour, which can make the cake tough and dense.
