Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

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.
Make the batter
In a large bowl, mix the powdered sugar and lard or butter until well combined.
Add the molasses and water or milk, and mix until smooth.
Stir in the baking soda.
Beat the eggs in a separate bowl, then add them to the mixture last.
Bake
Drop the batter into cups and bake in a moderate oven at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Powdered sugar
- Adds sweetness and a fine, tender crumb to the cupcakes.
- Lard or butter
- Provides fat that tenderizes the crumb and carries flavor.
- Molasses
- Adds deep sweetness, dark color, and moisture.
- Baking soda
- Reacts with the molasses acidity to produce gas that makes the cupcakes rise.
- Eggs
- Add structure and help bind the batter as it sets.
The step that matters
Adding the baking soda and eggs. Baking soda reacts with the acidic molasses right away, so the batter should be baked promptly to keep the gas that gives lift. Eggs add structure, and beating them separately before adding them last helps them mix in evenly without overworking the batter.
