German Tea Cake

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 sponge

  1. Combine yeast, water, and a portion of the flour to create a sponge.

  2. Let the sponge stand for three hours.

Make the dough

  1. Add the remaining flour, sugar, raisins, lemon zest, lemon juice, melted butter, and beaten egg whites to the sponge. Mix until a dough forms.

  2. Place the dough in a Turkshead mold.

  3. Let the dough stand for one hour.

Bake

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

  2. Bake until golden.

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

What each ingredient does

Flour
Forms the gluten network that gives the cake its structure.
Eggs
Add structure and richness, with whipped whites helping the crumb rise and set.
Yeast
Ferments the sponge, producing gas that makes the dough rise.
Butter
Adds fat for tenderness and a richer crumb.
Raisins
Add sweetness and chewy moisture throughout the cake.

The step that matters

Letting the sponge stand for three hours. The yeast needs time to ferment the flour and water. Under-fermenting leaves the dough dense and slow to rise, while the gas produced by fermentation gives the cake its lift.
