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 ↓
Corn and Graham Johnny Cake
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).
Make the batter
In a large bowl, mix the cornmeal, molasses, sour milk, graham flour, melted butter, all-purpose flour, baking soda, and salt.
Beat in the eggs until well combined.
Pour the batter into a greased baking dish.
Bake
Bake for 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 bulk of the batter and gives the johnny cake its coarse, grainy texture.
- Sour milk
- Its acidity reacts with baking soda so the batter rises and becomes tender.
- Baking soda
- Reacts with the acid in the sour milk and molasses to leaven the batter.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Molasses
- Adds sweetness, moisture, and a deep color and flavor to the cake.
- Melted butter
- Adds fat for moistness and a tender crumb.
The step that matters
Adding the baking soda with the sour milk and molasses. Baking soda needs an acid to react and leaven the batter; mixing it thoroughly with the acidic sour milk and molasses ensures even rising and prevents pockets of soda or a bitter, dense result.
