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 ↓
Helen's Ginger Cookies
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 large bowl, cream together the sugar, molasses, shortening, lard, and butter.
Dissolve the vinegar in cold water and add it to the mixture.
Mix the baking soda into the boiling water and add it to the bowl.
Stir in the ginger and gradually add flour until the dough is soft enough to roll.
Incorporate the egg into the dough.
Bake
Preheat the oven to 400°F (200°C).
Bake the cookies.

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
- Molasses
- Adds dark sweetness, moisture, and a rich flavor that suits the ginger.
- Baking soda
- Reacts with the vinegar and hot water to lighten the dough and help it rise.
- Shortening
- Adds fat that keeps the cookies tender and affects their texture.
- Lard
- Adds fat that contributes to a tender, short texture.
- Egg
- Binds the dough and adds structure as it bakes.
- Flour
- Provides the structure that lets the dough be rolled and hold its shape.
The step that matters
Dissolving the baking soda in boiling water and adding it to the dough. Baking soda needs moisture and an acid to react and produce gas. Adding it to the dough with the vinegar lets it lift the cookies. If it is not mixed in evenly, pockets of soda can leave bitter spots and uneven rising.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, butter, vinegar, flour, egg):
- Cinnamonfits better
- Nutmegfits better
- Allspicefits about as well
- Gingerthe original
Fit is the average pairing score against sugar, molasses, butter, vinegar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
