Rye Cakes for Tea

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).

  2. In a bowl, combine the rye flour and all-purpose flour.

  3. In a separate bowl, mix the sour milk and baking soda; let it foam.

Mix and bake

  1. Stir the foamed mixture into the flour mixture along with the salt and molasses.

  2. Mix until stiff, then transfer to a buttered pan.

  3. Smooth the top with a spoon dipped in hot water.

  4. Bake for 30 minutes.

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

What each ingredient does

Rye flour
Provides the dense, earthy structure and flavor that defines this cake.
All-purpose flour
Adds gluten-forming structure so the rye batter holds its shape while baking.
Sour milk
Its acidity reacts with the baking soda to produce gas that lifts the batter.
Baking soda
Reacts with the acidic sour milk to release carbon dioxide, giving the cake its rise.
Molasses
Adds sweetness, moisture, and a deep color and flavor to the cake.

The step that matters

Let the sour milk and baking soda foam. The acid-base reaction releases carbon dioxide that leavens the heavy rye batter. Letting it foam fully before mixing ensures the gas is produced before baking, so the cake rises properly.
