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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Beat the eggs separately.
Make the dough
Cream together the brown sugar, egg yolks, and molasses.
Add the sifted flour and salt to the mixture.
Fold in the beaten egg whites.
Finally, add the floured walnuts.
Bake
Drop by teaspoons onto greased baking sheets.
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks add richness and moisture, while beaten whites lighten the dough and help it rise.
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown and stay soft.
- Molasses
- Adds moisture, deep flavor, and a darker color to the cookies.
- Flour
- Provides the structure that holds the cookies together as they bake.
- Walnuts
- Add crunch and a toasty, nutty flavor throughout the cookies.
The step that matters
Folding in the beaten egg whites. Folding gently keeps the air in the whites, which lightens the dough. Stirring vigorously knocks the air out and leaves dense, flat cookies.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, molasses, egg, flour):
- Almondfits better
- Chestnutfits better
- Hazelnutfits about as well
- Walnutthe original
Fit is the average pairing score against sugar, molasses, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
