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 ↓
Aunt Lizzie's Gingerbread
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the dough
In a large bowl, mix the milk, molasses, and flour together.
Melt the butter and add it to the mixture.
Roll out the dough into sheets.
Bake
Cut into desired shapes and bake until golden.

Flour and butter 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
- All-purpose flour
- Provides the main structure that holds the dough together once baked.
- Unsalted butter
- Adds fat for tenderness and a rich texture in the cookies.
- Molasses
- Adds sweetness, moisture, and the deep flavor and dark color typical of gingerbread.
- Milk
- Adds moisture so the flour hydrates and the dough can be rolled out.
- Baking soda
- Reacts with the molasses's acidity to lift the cookies slightly and aid browning.
The step that matters
Cut into desired shapes and bake until golden. Baking time depends on thickness and oven accuracy, and over-baking dries molasses cookies and makes them brittle, while under-baking leaves them soft and doughy in the centre.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
