Why it works: Flour and butter 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 ↓

Directions
Make the dough
Sift together 3 cups flour, 1 teaspoon salt, 3 tablespoons sugar, and 3 scant teaspoons baking powder.
Rub in 2 heaping teaspoons butter.

Spread batter 1 inch thick on well-buttered pans.
Add the topping and bake
Mix together 2 tablespoons flour, 1 heaping teaspoon cinnamon, and 4 tablespoons sugar.
Rub in 2 tablespoons butter until crumbly.
Spread the crumbly mixture thickly on top of the dough.
Bake about 2 hours in a moderate oven.

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 sets the batter into a sliceable cake.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Baking powder
- Releases gas during baking so the batter rises and becomes light.
- Butter
- Adds fat that tenderizes the crumb and helps the topping turn crumbly.
- Sugar
- Sweetens the cake and helps the topping brown as it bakes.
The step that matters
Spread the batter 1 inch thick. The batter is stiff and must fill the pans evenly to a set depth; uneven spreading gives uneven rising and baking, so thin spots can dry out while thick spots stay underbaked.
