Why it works: Sugar and molasses 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 ↓

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.
Make the dough
In a bowl, beat the egg and mix in the sugar and molasses.
Add the ginger, baking soda, vinegar, and salt; mix well.
Gradually add flour until the dough is stiff enough to roll.
Shape and bake
Roll out the dough and cut into desired shapes.
Bake in a hot oven at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the dough and adds richness and structure to the cookies.
- Molasses
- Adds moisture, deep flavor, and a dark color to the cookies.
- Baking soda
- Reacts with the acid in the vinegar and molasses to lighten the dough and help it rise.
- Vinegar
- Acidifies the dough so the baking soda reacts and the cookies rise and soften.
- Flour
- Provides the structure that lets the dough hold its shape when rolled and cut.
The step that matters
Adding the flour gradually. Flour must be added slowly until the dough is just stiff enough to roll. Too much flour makes the cookies dry and tough, while too little leaves the dough sticky and hard to cut cleanly.
Swap the ginger
How well each one fits the dish's main ingredients (egg, sugar, molasses, vinegar, flour):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits about as well
- Gingerthe original
Fit is the average pairing score against egg, sugar, molasses, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
