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 rye flour, wheat flour, and coarse sea salt.

  3. In another bowl, mix sour milk and baking soda; let it foam.

Mix and bake

  1. Stir the foaming mixture into the flour mixture along with 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
Forms a dense, moist crumb with less gluten structure than wheat flour.
Wheat flour
Adds gluten for some structure and a lighter crumb than rye alone.
Sour milk
Supplies liquid and acidity that reacts with the baking soda.
Baking soda
Reacts with the acidic sour milk to release gas that lifts the cake.
Molasses
Adds sweetness, moisture, and a dark color and deep flavor.

The step that matters

Let the sour milk and baking soda foam before mixing. The acid-base reaction releases carbon dioxide bubbles that give the cake its lift. Waiting for the foam to form before combining ensures the leavening is active in the batter.
