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 ↓
Soda Batter Cakes
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the eggs well with the sour milk.
Add the bicarbonate of soda and gradually stir in enough flour to make a stiff batter.
Let the batter rise until smooth.
Bake and serve
Divide the batter into equal portions and lay them on a floured baking sheet, spaced apart.
Bake in a brisk oven at 400°F (200°C) until cooked.
Serve immediately on a hot dish with a folded napkin, and enjoy cut open with butter.

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 to the cakes as they cook.
- Sour milk
- Provides moisture and acidity that reacts with the bicarbonate of soda to lighten the batter.
- Bicarbonate of soda
- Reacts with the acid in the sour milk to release gas, making the cakes rise.
- Flour
- Forms the stiff batter's structure, setting as the cakes bake.
The step that matters
Let the batter rise until smooth. Bicarbonate of soda begins releasing gas as soon as it meets the sour milk's acid, so the batter should be shaped and baked promptly to keep that lift. Waiting too long lets the gas escape, leaving flatter cakes.
