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 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).
In a large bowl, combine cornmeal, flour, baking soda, cream of tartar, and salt.
In another bowl, whisk together the eggs, sweet milk, molasses, and melted butter.
Mix and bake
Pour the wet ingredients into the dry ingredients and mix until just combined.
Pour the batter into square baking tins.
Bake for 30-40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornmeal
- Provides the main structure and the coarse, grainy texture of the bread.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Baking soda
- Reacts with the acid in the batter to produce gas that lifts the cake.
- Cream of tartar
- Acidifies the batter and works with baking soda to help it rise.
- Molasses
- Adds sweetness, dark color, and a deep flavor to the cake.
- Sweet milk
- Hydrates the dry ingredients and adds moisture and tenderness.
The step that matters
Mix until just combined. Once the wet and dry ingredients meet, baking soda and cream of tartar start reacting. Overmixing develops gluten from the flour and toughens the cake, so stop as soon as no dry streaks remain.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
