Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Filled Cookies
Ingredients
Directions
Make the dough
Combine shortening, sugar, egg, and sweet milk with dissolved baking soda in a bowl.
Sift flour with cream of tartar, add vanilla, and mix well.
Roll out the dough thin and cut with a cookie cutter.
Make the filling
Cook chopped raisins with water, flour, and lemon juice in a saucepan until thick.
Assemble and bake
Place a teaspoon of the filling on one cookie and cover with another.
Bake until brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Shortening
- Adds fat that keeps the cookie dough tender and rich.
- Flour
- Provides the structure that holds the dough and filling together.
- Baking soda
- Reacts with the acidic cream of tartar to lift the cookies.
- Cream of tartar
- Provides acidity that reacts with baking soda so the cookies rise.
- Raisins
- Supply sweetness and moist body to the filling.
- Egg
- Binds the dough and adds richness and structure.
The step that matters
Cook the raisin filling until thick. The filling must be cooked long enough to thicken fully, because flour sets only when heated. A thin filling will soak into the dough and run out during baking.
