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 ↓
Thin Ginger Snaps
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Beat the butter until creamy.
Gradually add the sugar and beat until very light.
Dissolve the baking soda in the milk, then add it along with the ginger to the butter mixture.
Gradually mix in the flour until combined.
Bake and cut
Butter iron baking sheets and spread the mixture very thinly on them.
Bake until brown, then cut into 2-inch squares while hot.

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 and richness, and helps the cookies crisp as they bake.
- Sugar
- Sweetens and, when beaten with butter, helps create a light texture.
- Flour
- Provides the structure that holds the thin cookies together.
- Baking soda
- Reacts with the milk to lift the dough and aid browning.
- Ground ginger
- Adds the spicy aroma and flavor that defines the cookie.
The step that matters
Spreading the mixture very thinly. Thin spreading lets the dough bake through and crisp evenly. A thick layer would stay soft in the centre and not give the snap this recipe is named for.
Swap the ginger
How well each one fits the dish's main ingredients (butter, sugar, milk, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against butter, sugar, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
