Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Batter Cakes
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.
Make the batter
Beat the eggs in a bowl.
Add salt, sugar, and sour milk.
Gradually mix in flour until a batter forms.
Dissolve baking soda in a little warm water and stir it into the batter.
Bake
Bake immediately in a preheated oven at 350°F (175°C).
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
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 heat.
- Sour milk
- Supplies liquid and acidity, which reacts with the baking soda to lighten the batter.
- Flour
- Forms the gluten network and framework that gives the cakes their body.
- Baking soda
- Reacts with the acid in the sour milk to release carbon dioxide, making the cakes rise.
- Sugar
- Adds sweetness and helps the surface brown during baking.
The step that matters
Bake immediately after adding the baking soda. Baking soda starts releasing carbon dioxide as soon as it meets the acid in the sour milk. If the batter waits, many of the bubbles escape before the heat sets the batter, so the cakes rise less.
“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.
