Sand 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

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

Make and shape the dough

  1. In a bowl, combine butter, vinegar, and flour to form a stiff dough.

  2. Roll out the dough and cut into desired shapes.

Top and bake

  1. Brush the tops with the beaten egg.

  2. Sprinkle sugar, cinnamon, and nuts on top.

  3. Bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Fat that keeps the dough short and tender rather than tough.
Flour
Provides the structure that holds the stiff dough and its shapes.
Egg
Brushed on top to give a glossy sheen and help the surface brown.
Sugar
Sprinkled on top, it sweetens and caramelizes to add browning and crunch.

The step that matters

Bake until golden. Golden color is the only cue for doneness here. Sugar browns quickly through caramelization and the Maillard reaction, so pulling the tarts once they are golden keeps them from drying out and turning bitter.

Swap the nuts

How well each one fits the dish's main ingredients (butter, vinegar, flour, egg, sugar, cinnamon):

  1. Almondfits better
  2. Chestnutfits better
  3. Cashew nutfits better
  4. Nutsthe original

Fit is the average pairing score against butter, vinegar, flour, egg, sugar, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
