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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Beat together the butter and sugar until creamy.
Add the molasses, cream of tartar, baking soda, milk, and yellow ginger; mix well.
Gradually add flour until a stiff dough forms.
Roll the dough to about ¼ inch thick.
Cut and bake
Cut with a small glass and place on a baking sheet.
Bake in a preheated oven at 400°F (200°C) until hard.

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
- Butter
- Adds fat that creams with sugar to create tenderness and richness in the cookie.
- Molasses
- Provides moisture, deep flavour, and dark colour while keeping the cookies chewy.
- Baking soda
- Reacts with the acidic molasses and cream of tartar to lift and spread the dough.
- Cream of tartar
- Adds acidity that works with baking soda to help the cookies rise and stay light.
- Flour
- Provides structure so the dough holds its shape when rolled and cut.
The step that matters
Bake until hard. Baking only until the edges are set and the surface is firm matters because ginger snaps keep crisping as they cool. Overbaking can make them bitter and too brittle, while underbaking leaves them soft and doughy in the centre.
Swap the ginger
How well each one fits the dish's main ingredients (butter, sugar, molasses, cream, milk, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Jalapenofits about as well
Fit is the average pairing score against butter, sugar, molasses, cream, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
