Why it works: Milk and butter 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 slow 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).
Mix and bake
In a large bowl, mix together the molasses, sweet milk, butter, flour, eggs, and ammonia until well combined.
Pour the mixture into section pans.
Bake in the preheated oven until done.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds sweetness, moisture and the dark color and rich flavor of gingerbread.
- Flour
- Provides the structure that holds the batter together as it bakes.
- Eggs
- Add structure and help bind the batter while it sets in the oven.
- Butter
- Adds fat, which tenderizes the crumb and carries flavor.
- Sweet milk
- Adds moisture and hydrates the flour so the batter can set.
- Ammonia
- Acts as a leavening agent, releasing gas that lightens the batter as it bakes.
The step that matters
Bake soon after mixing in the ammonia. Ammonia-based leaveners release gas once they are wet and warm, so the lift is strongest when the batter goes into the hot oven right after mixing. Waiting lets much of that gas escape before the structure sets, which can leave a dense, flat result.
