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 your oven to 400°F (200°C).
In a large bowl, beat together the sugar and eggs until well combined.
Add the milk and baking powder, then mix in the flour until smooth.
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 main structure that sets the cake as it bakes.
- Eggs
- Add structure and richness, helping the cake hold its shape.
- Milk
- Adds moisture and helps form a smooth, pourable batter.
- Granulated sugar
- Adds sweetness and helps the crumb brown in the oven.
- Baking powder
- Releases gas that makes the batter rise and lighten as it bakes.
The step that matters
Letting the batter rise. The batter needs its full rise time in a warm spot so the baking powder can build bubbles. Rushing this step can leave the cake dense and flat.
“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.
