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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Sift the flour, baking powder, sugar, and salt together four times.
Pour in the boiling milk and beat until smooth.
Carefully fold in the beaten egg whites.
Bake in a moderate oven at 350°F (175°C) without greasing the tin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the light, airy crumb together.
- Egg whites
- Whipped foam gives the cake its lift and light, spongy texture.
- Baking powder
- Releases gas during baking so the batter rises and becomes airy.
- Sugar
- Sweetens the cake and helps stabilise the egg white foam.
- Milk
- Adds moisture and helps the flour hydrate into a smooth batter.
The step that matters
Carefully fold in the beaten egg whites. Egg white foam traps the air that makes the cake rise. Stirring or deflating it during folding knocks out that air, leaving a dense, flat cake.
“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.
