Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 3% of all ingredient pairs, and 35,031 recipes mention both. Both carry beta-damascenone, which smells apple, rose. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the dough
Knead the flour, butter, sugar, vanilla sugar, and egg into a dough.
Chill the dough for a while.
Roll out the dough to about ¼ cm thick.
Shape and bake
Cut round cookies out of the dough.
For half the cookies, cut a small shape out of the middle—these will be the tops.
Place the cookies on a greased tray and bake at 150°C for about 20 minutes.
Let the cookies cool.
Ice and assemble
Combine the powdered sugar and water to make a smooth icing.
Carefully dip the top cookies in the icing to coat one face.
Spread some jam on the bottom layer cookies.
Top with the iced cutout cookies.

Sugar and vanilla share little aroma chemistry, yet 35,031 recipes mention both: they likely 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
- Provides the structure that holds the dough together after baking.
- Butter
- Adds fat for a tender, crumbly texture and rich flavour.
- Egg
- Binds the dough and adds richness and structure.
- White granulated sugar
- Sweetens the dough and helps the cookies brown during baking.
- Jam
- Adds sweetness and fruity flavour between the cookie layers.
The step that matters
Carefully dip the top cookies in the icing. Icing made from powdered sugar and a little water is thin and can run off or pool if too wet, so it should be smooth and used just to coat one face of each cookie.
Flavor stand-ins for the vanilla
How well each one fits the dish's main ingredients (flour, sugar, egg, butter):
- Vanillathe original
- Raisinabout as good a flavor fit
Fit is the average pairing score against flour, sugar, egg, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
