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 ↓

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.
Make the batter
In a bowl, mix together the sugar, molasses, melted butter, salt, cinnamon, and mixed spices.
Add the beaten egg and sour milk, and stir well.
Sift the baking soda and flour into the mixture, then beat for about 2 minutes.
Bake
Pour the batter into a greased 9‑inch square pan, about 1.5 inches deep.
Sprinkle sugar on top and bake for 40 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the main structure that sets the crumb as the batter bakes.
- Baking soda
- Reacts with the sour milk to produce gas that lifts the batter.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tenderness.
- Molasses
- Adds moisture, dark color, and a deep sweetness typical of gingerbread.
- Egg
- Binds the batter and adds structure and richness to the crumb.
- Melted butter
- Adds fat for a tender texture and moist crumb.
The step that matters
Sifting the baking soda and flour, then beating. Baking soda must be evenly distributed so it reacts with the acidic sour milk, giving an even rise. Beating for a short time develops enough structure without making the crumb tough.
