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 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 your oven to 350°F (175°C).
Make the dough
In a bowl, mix the egg, brown sugar, molasses, lard or butter, sour milk, baking soda, and ground ginger.
Add any additional spices to suit your taste.
Mix until soft, then break off small pieces of dough.
Shape and bake
Roll and flatten each piece with your hand.
Place the cookies on a baking pan and bake until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds dark color, moisture and a rich, sweet flavor to the cookies.
- Lard or butter
- Provides fat for tenderness and a richer mouthfeel in the dough.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce lift and a softer crumb.
- Sour milk
- Its acidity reacts with baking soda for rising and adds tang that balances sweetness.
- Brown sugar
- Adds sweetness, moisture and browning to the cookies.
- Egg
- Binds the dough and adds structure as the cookies set.
The step that matters
Shape and bake until done. Baking soda reacts with acidic sour milk and molasses as soon as the dough is mixed, so bake promptly after shaping. Flattened pieces spread in the oven, so leaving space matters for even cookies.
Swap the ginger
How well each one fits the dish's main ingredients (egg, sugar, molasses, butter, milk):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Clovefits about as well
Fit is the average pairing score against egg, sugar, molasses, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
