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 ↓
Banberry 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.
Make the dough
Preheat the oven to 350°F (175°C).
In a bowl, mix flour and lard to create a rich pie crust.
Roll the dough thin and cut out circles using a 5-inch saucer.
Fill and shape
In another bowl, combine the egg, lemon juice, chopped raisins, sugar, salt, and flour to make the filling.
Place a good teaspoon of filling in the center of each dough circle.
Pinch the edges to seal the tarts.
Bake
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.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- All-purpose flour
- Forms the gluten structure that gives the crust its body.
- Lard
- Coats the flour so the crust stays tender and flaky.
- Egg
- Sets when heated, binding the raisin filling together.
- Lemon juice
- Adds acidity that brightens the sweet raisin filling.
- Raisins
- Provide sweetness and chewy, moist texture in the filling.
- Sugar
- Sweetens the filling and helps the tarts brown as they bake.
The step that matters
Pinch the edges to seal the tarts. A tight seal keeps the filling inside while baking. Gaps let juices leak out, where they can burn and leave the tarts dry.
Swap the lemon
How well each one fits the dish's main ingredients (flour, egg, raisin, sugar):
- Vanillafits better
- Figfits better
- Lemonthe original
- Datesfits about as well
Fit is the average pairing score against flour, egg, raisin, sugar. Candidates are from the same food group and used in at least 100 recipes.
“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.
