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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make and bake
In a bowl, mix molasses, sugar, sour milk, butter, baking soda, and ginger.
Gradually add flour until a soft dough forms.
Drop spoonfuls of dough onto a baking sheet.
Bake in the hot oven until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 a deep flavour that gives the cookies their character.
- Sour milk
- Its acidity reacts with the baking soda so the cookies rise and turn tender.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas, lifting the dough.
- Butter
- Adds fat for richness and a tender texture.
- Flour
- Provides the structure that holds the soft dough together as it bakes.
The step that matters
Bake in the hot oven until golden brown. Baking soda starts producing gas as soon as it meets the acidic liquids, so the dough should go into the hot oven promptly. Pulling the cookies when golden brown keeps them from drying out while the sugars caramelise for flavour and colour.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, milk, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Jalapenofits about as well
Fit is the average pairing score against molasses, sugar, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
