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 the dough

  1. In a bowl, cream together the sugar and butter.

  2. Add the flour and eggs, mixing until well combined.

  3. Roll out the dough thinly.

Top and bake

  1. Spread the egg white on top of the rolled dough.

  2. Press walnut kernels into the top.

  3. Bake until lightly golden.

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

What each ingredient does

Butter
Creams with sugar to add richness, tenderness and a short, crumbly texture.
Flour
Provides the structure that holds the dough together and lets it be rolled thin.
Eggs
Bind the dough and add richness; the reserved white gives a glossy, crisp top.
Sugar
Sweetens the dough and helps it brown lightly in the oven.
Walnut kernels
Add nutty flavour and a crunchy topping once pressed into the dough.

The step that matters

Roll out the dough thinly. A thin layer bakes through and crisps evenly. Thick dough stays soft in the middle and can brown unevenly before it is cooked through.

Swap the walnut

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

  1. Almondfits better
  2. Macadamia nutfits better
  3. Chestnutfits about as well
  4. Walnutthe original

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