Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Speculaas
Ingredients
Directions
Make the dough
Cream butter, sugar, salt, and spices until a soft mass forms.
Add the egg and both flours, mixing into a soft dough.
(Optional) Rest the dough for 2 days in the fridge to intensify spice flavor.
Shape the cookies
Sprinkle flour onto the speculaas mold to prevent sticking.
Press a piece of dough into the mold, cutting excess dough with a string or knife, keeping it flat against the template.
Flip the mold over and smack it forcefully face-down on the kitchen worktop to release the speculaas.
Arrange the speculaas on a well-buttered baking sheet, leaving space between them for spreading.
Bake and serve
Bake at 170 °C; small cookies bake 20 min, larger ones 30 min or more. Check doneness by cooling a cookie and smelling for crispness.
Let the speculaas cool completely before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries fat for a crumbly, tender texture and rich flavor.
- Light brown sugar
- Adds sweetness and molasses notes, and helps the cookies brown.
- Egg
- Binds the dough and adds structure and richness.
- Flour
- Provides the main structure that holds the cookie shape.
- Self-raising flour
- Contains leavening so the cookies rise slightly and stay light.
The step that matters
Pressing the dough into the mold. Pressing too little or too much dough, or leaving it uneven, gives thin or unclear designs and uneven baking. Dusting the mold with flour prevents sticking and keeps the detail sharp.
“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.
