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 ↓
Molasses Cookies
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix the molasses and lard together, then add the salt and ginger.
Dissolve the baking soda in the cold water and add it to the mixture.
Stir in enough flour to form a firm batter.
Shape and bake
On a floured surface, roll out part of the dough to about ⅛ inch thick.
Cut into round cookies and bake in a 400°F (200°C) oven.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides the dark color, rich flavor and moisture that define the cookie.
- Lard or drippings
- Adds fat for tenderness and a short, crisp texture.
- Baking soda
- Reacts with the molasses acidity to lift and lighten the cookie.
- Flour
- Forms the structure that holds the dough together for rolling.
- Brown sugar
- Adds sweetness and moisture, supporting browning and a soft chew.
The step that matters
Dissolve the baking soda in the cold water. Baking soda must be fully dissolved so it spreads evenly through the dough; undissolved pockets can cause bitter spots and uneven rising.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, flour):
- Cinnamonfits better
- Jalapenofits better
- Gingerthe original
- Nutmegfits about as well
Fit is the average pairing score against molasses, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
