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 ↓
Butter Dough Tarts
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a bowl, cream the butter and sugar together until light and fluffy.
Add the lemon rind, milk, baking powder, and eggs, mixing well.
Gradually add flour until a soft dough forms.
Roll out the dough and cut it into squares.
Shape and bake
Fill each square with raisins and nuts, then shape them into horns.
Brush the tops with beaten egg and sprinkle with nuts.
Bake in the preheated oven until golden 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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Butter
- Creamed with sugar to trap air and add richness and tenderness to the dough.
- Eggs
- Bind the dough and add structure, while the beaten egg wash helps the tops brown.
- Flour
- Forms the structure of the dough once gradually added to the creamed mixture.
- Baking powder
- Releases gas in the dough so the tarts rise and become lighter.
- Sugar
- Sweetens the dough and, creamed with butter, helps it turn light and fluffy.
The step that matters
Creaming the butter and sugar. Beating until light and fluffy traps air in the fat, which helps the dough rise and become tender. Under-creaming leaves a denser tart.
Swap the nuts
How well each one fits the dish's main ingredients (butter, lemon, sugar, flour, milk, egg, raisin):
- Almondfits better
- Pistachiofits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against butter, lemon, sugar, flour, milk, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
