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.
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 a greased square baking tin.
Bake for about 30-40 minutes or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornmeal
- Forms the main body of the cake and gives it its characteristic grainy texture.
- Eggs
- Bind the batter and add structure as they set in the oven.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that lifts the batter.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda, helping the cake rise.
- Molasses
- Adds sweetness, moisture, and browning from its sugars.
- Sweet milk
- Hydrates the dry ingredients and helps form the batter's structure.
The step that matters
Mix until just combined. Overmixing the batter develops gluten in the flour, which can make the cake tough and dense. Stop once no dry streaks remain.
