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 ↓

Ingredients
Directions
Make the dough
Cream the butter and sugar together.
Add the eggs one at a time, mixing well after each addition.
Stir in the milk and baking powder.
Gradually add flour until a stiff dough forms.

Make the filling and bake
Prepare the filling by boiling the dates, water, and sugar until soft, then cool.
Spread the filling between two rolled-out dough pieces and bake.

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 dough richness and a tender crumb.
- Eggs
- Bind the dough and add structure as they are beaten in.
- Baking powder
- Releases gas in the dough, helping the cookies rise and lighten.
- Dates
- Cook down into a sweet, soft filling that gives the cookies their moisture and flavor.
The step that matters
Boiling the date filling until soft. The dates must cook long enough to break down into a spreadable paste; undercooked filling stays firm and can make the cookies uneven or wet when baked.
Swap the dates
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Datesthe original
Fit is the average pairing score against butter, sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
