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
Preheat the oven to 400°F (200°C).
In a bowl, mix the sugar, flour, and baking powder thoroughly.
Make the batter
Break the eggs into the mixture and beat them lightly.
Add the sweet milk or water and stir quickly until combined.
Pour the batter into a dripping pan and sprinkle sugar on top.
Bake
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness as they set, helping the cake hold its airy crumb.
- Baking powder
- Releases gas in the batter, lifting the cake as it bakes.
- Flour
- Forms the structure that holds the cake's shape as it sets.
- Sugar
- Sweetens the cake and helps it brown at the surface.
- Sweet milk or water
- Adds moisture to hydrate the flour and form a loose batter.
The step that matters
Stir quickly after adding the liquid. Once flour is moistened, gluten begins to develop, and overmixing makes the sponge tough and dense rather than light. Baking powder also starts releasing gas once wet, so the batter should go into the oven without delay.
