Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Cream the butter using your hands.
Gradually add the sugar while beating.
Add the eggs one at a time, beating vigorously after each addition.
When the mixture is creamy, add the flour.
Bake
Bake in a slow oven at 300°F (150°C) for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar, it traps air and gives the cake a tender, rich crumb.
- Granulated sugar
- Sweetens the cake and, beaten with butter, helps hold air for a light texture.
- Eggs
- Add structure and richness, and their emulsifying proteins bind butter and sugar into a smooth batter.
- Flour
- Provides the structure that sets the cake as the proteins and starches cook.
The step that matters
Adding the eggs one at a time. Adding eggs slowly lets each one emulsify fully into the creamed butter and sugar. Adding them too fast can cause the batter to curdle or separate, which affects the final texture.
“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.
