Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Ratafia Cookies
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.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, cream together the butter and sugar.
Add the milk and beaten eggs, mixing well.
In another bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture until combined.
Shape and bake
Roll out the dough very thin on a floured surface.
Cut into small cakes and place on a baking sheet.
Wet the tops with ratafia and dust with white sugar.
Bake until lightly golden.

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 give the cookies richness and a tender texture.
- Sugar
- Sweetens the cookies and helps create a crisp, golden surface when baked.
- Eggs
- Bind the dough and add structure and richness.
- All-purpose flour
- Forms the main structure of the dough once combined with the liquids.
- Baking powder
- Releases gas in the oven so the cookies rise slightly and lighten.
The step that matters
Roll out the dough very thin. Thin dough bakes through quickly and browns lightly. Thick pieces stay doughy in the center and can over-brown at the edges before they are set.
“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.
