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 400°F (200°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
Preheat your oven to 400°F (200°C).
In a large bowl, rub the butter into the flour until it resembles coarse crumbs.
Dissolve the sugar in the boiling water and let it cool.
Make and shape the dough
Once cool, mix the syrup with the flour and butter mixture as if making pastry.
Roll the dough very thin and cut into desired shapes.
Bake
Bake until crisp and light, about 10-12 minutes.

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
- All-purpose flour
- Forms the main structure of the dough once combined with liquid.
- Unsalted butter
- Rubbed into the flour to tenderize the dough and give a crisp, short texture.
- Granulated sugar
- Dissolved in boiling water to make a syrup that sweetens and helps the cookies brown.
- Baking soda
- Reacts with the syrup to lighten the dough and help the cookies turn crisp and light.
The step that matters
Rolling the dough very thin. Thin dough bakes through and turns crisp; thick dough stays soft and dense in the centre. Even thickness also helps the cookies bake at the same rate.
Swap the vanilla
How well each one fits the dish's main ingredients (flour, sugar, butter):
- Raisinfits better
- Vanillathe original
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against flour, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
