Why it works: Molasses and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Ginger Snaps
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, mix together the butter or beef drippings, molasses, brown sugar, ground ginger, and baking soda dissolved in cold water until well combined.
Gradually add the flour, sifting it after measuring, and mix until a dough forms.
If using butter or fat from corned beef, add a pinch of salt.
If using lard or beef drippings, add salt to taste.
Shape and bake
Roll out the dough to ⅛ inch thick and cut with a 2-inch cutter.
Transfer the cookies to the inverted bottom of buttered baking tins using a broad knife or cake turner.
Bake in a preheated oven at 350°F (175°C) until lightly browned, being careful not to burn.
Store
Store the snaps in airtight glass jars in a dry place.

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 or beef drippings
- Adds fat that tenderises the cookie and carries the flavour.
- Molasses
- Provides moisture, deep sweetness and a dark colour to the cookie.
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown and crisp.
- Baking soda
- Reacts with the molasses's acidity to lighten the dough and help it spread.
- All-purpose flour
- Provides the structure that holds the dough together and sets the cookie.
The step that matters
Bake until lightly browned, not burnt. Molasses and sugar darken quickly, so the cookies can turn bitter once scorched. Pulling them when lightly browned keeps them crisp and flavourful.
Swap the ginger
How well each one fits the dish's main ingredients (butter, molasses, sugar, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against butter, molasses, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
