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 moderate oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Mix the batter
In a mixing bowl, combine sour milk, salt, and sugar.
Beat the eggs until light and add to the mixture.
Dissolve the baking soda in a little cold water and stir it into the bowl.
Sift together the flour and Indian meal, then add to the bowl along with melted butter.
Stir all ingredients together until well combined.
Bake
Pour the batter into well buttered tins.
Bake at 400°F (200°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Baking soda
- Reacts with the acidic sour milk to release gas, helping the cakes rise.
- Sour milk
- Its acidity activates the baking soda and adds tenderness and moisture.
- Indian meal
- Cornmeal that gives the cakes their coarse, grainy texture and structure.
- Melted butter
- Adds fat for richness and a tender crumb.
The step that matters
Dissolve the baking soda in cold water. Baking soda needs to be evenly dispersed so it reacts with the sour milk throughout the batter. Lumps leave pockets of bitter residue and uneven rising.
“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.
