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 ↓

Ingredients
Directions
The book says “a cool oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a large bowl, beat the butter and sugar until light and fluffy.
Whisk the eggs until frothy, then stir them into the butter and sugar mixture.
Gradually add the flour and baking soda, mixing until just combined.
Bake
Pour the batter into a greased cake pan and bake immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter and sugar
- Beating them together traps air, giving the cupcake a light, fluffy crumb.
- Eggs
- Add structure and richness, binding the batter as they set in the oven.
- All-purpose flour
- Forms the main structure of the crumb as its proteins set during baking.
- Baking soda
- Reacts with acidity in the batter to release gas, helping the cake rise.
The step that matters
Pour the batter and bake immediately. Baking soda starts releasing gas as soon as it meets moisture and acid, so a delay lets bubbles escape and can leave the cake flat and dense.
