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 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.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
In a large bowl, mix together molasses, sugar, lard, sour milk, eggs, vinegar, salt, ginger, and baking soda.
Gradually add flour until the mixture is soft and manageable.
Bake
Drop spoonfuls of the dough onto a baking sheet.
Bake in the preheated oven until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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 color, moisture and a rich, sweet flavor.
- Lard
- Adds fat, which tenderizes the cookies and carries flavor.
- Eggs
- Bind the dough and add structure as they set in the oven.
- Baking soda
- Reacts with the acidic sour milk and vinegar to make the cookies rise and brown.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tang.
- Flour
- Provides the structure that holds the dough together as it bakes.
The step that matters
Gradually add flour until the mixture is soft and manageable. Too much flour makes the dough stiff and the cookies dense and dry, while too little leaves them spreading thin. Adding it gradually lets you stop when the dough reaches the right soft consistency.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, milk, egg, vinegar, flour):
- Cinnamonfits better
- Nutmegfits better
- Allspicefits about as well
- Gingerthe original
Fit is the average pairing score against molasses, sugar, milk, egg, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
