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. Cream the butter and sugar together until light and fluffy.

  2. Add the eggs, reserving the whites of 2 eggs for later.

  3. Mix in enough flour to form a very soft dough.

  4. Drop spoonfuls of the dough onto a baking sheet.

Bake and serve

  1. Spread the reserved egg whites over the tops of the cakes.

  2. Sprinkle with sugar and cinnamon.

  3. Bake until lightly golden.

  4. Allow to cool before serving.

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.

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 trap air, giving the cookies a tender, rich texture.
Sugar
Creams with butter for a light structure and adds sweetness and crisp browning on top.
Eggs
Add moisture and structure, and the whites give the tops a glossy finish.
Flour
Provides the structure that holds the very soft dough together as it bakes.

The step that matters

Mix in enough flour to form a very soft dough. Too little flour makes the dough spread too much, while too much makes the cookies dry and dense. The dough should be soft but still hold its shape when dropped.

Swap the cinnamon

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

  1. Cinnamonthe original
  2. Nutmegfits about as well
  3. Jalapenofits less well
  4. Capersfits less well

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