German Sand Tart

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 batter

  1. In a large bowl, beat together the powdered sugar, flour, and butter.

  2. Add the eggs and lemon juice alternately, mixing well.

  3. Stir the batter in the same direction for 1 hour.

Bake

  1. Butter the inside of a cake mold and coat it thickly with fine Zwieback or cracker crumbs.

  2. Pour the batter into the prepared mold and bake for 1 hour.

  3. For a variation, bake in 2 layers and fill with jelly, then top with rum icing.

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

What each ingredient does

Butter
Adds richness and tenderness, and helps the batter bake with a fine, dense crumb.
Eggs
Provide structure and binding as the batter sets in the oven.
Flour
Forms the structure that holds the cake together as it bakes.
Powdered sugar
Sweetens the cake and dissolves smoothly into the butter for a fine texture.
Lemon juice
Adds acidity that brightens the flavor and balances the sweetness.

The step that matters

Stirring the batter in one direction for 1 hour. Long, steady mixing develops gluten and builds air into the batter, so the cake sets with a dense but even crumb. Stirring in alternating directions or stopping early can leave uneven texture.

Swap the lemon

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