Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the dough
Preheat your oven to 350°F (175°C).
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the molasses and vanilla or spices.
In a separate bowl, combine the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Shape and bake
Roll the dough very thin on a floured surface.
Cut into desired shapes and place on a baking sheet.
Bake for 8-10 minutes or until lightly golden.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Butter
- Creams with sugar to trap air, giving the cookies a light, tender texture and rich flavor.
- Eggs
- Bind the dough and add structure and richness as they are beaten in one at a time.
- Flour
- Provides the main structure that holds the cut shapes together during baking.
- Baking soda
- Reacts with the molasses to lift the dough and help it brown.
- Molasses
- Adds moisture, deep flavor, and a darker color to the cookies.
The step that matters
Mixing the dry ingredients into the wet mixture. Mixing only until just combined keeps the dough tender. Overmixing develops gluten in the flour, which can make the cookies tough.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, egg, butter, flour, molasses):
- Raisinfits better
- Vanillathe original
- Figfits less well
- Datesfits less well
Fit is the average pairing score against sugar, egg, butter, flour, molasses. Candidates are from the same food group and used in at least 100 recipes.
