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

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, mix flour and lard to create a rich pie crust.

  3. Roll the dough thin and cut out circles using a 5-inch saucer.

Fill and shape

  1. In another bowl, combine the egg, lemon juice, chopped raisins, sugar, salt, and flour to make the filling.

  2. Place a good teaspoon of filling in the center of each dough circle.

  3. Pinch the edges to seal the tarts.

Bake

  1. Bake in the preheated oven until golden brown.

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):

  1. Vanillafits better
  2. Figfits better
  3. Lemonthe original
  4. 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.
