Why it works: Flour and milk 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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat oven to 400°F (200°C).
Beat sugar and eggs together until well combined.
Add milk and yeast (or baking powder) to the mixture and stir.
Gradually mix in the flour until a smooth batter forms.
Cover the bowl and let the batter rise in a warm place for 2 hours.
Bake
Pour the batter into a greased baking pan and bake for about 25-30 minutes or until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the starch and gluten structure that holds the cake together as it bakes.
- Eggs
- Bind the batter and set during baking to give the cake its structure and richness.
- Milk
- Adds moisture and liquid so the flour hydrates into a smooth, pourable batter.
- Sugar
- Sweetens the cake and helps it brown through caramelization and the Maillard reaction.
- Yeast or baking powder
- Produces gas bubbles that lift the batter so the cake rises and becomes light.
The step that matters
Letting the batter rise. The rise needs a warm place and full time so the leavening can create bubbles; a cold or short rise leaves the cake dense. The rise is the step most likely to be rushed or skipped.
