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 the batter
Preheat the oven to 350°F (175°C).
In a bowl, combine rye flour, wheat flour, and salt.
In another bowl, mix sour milk and baking soda; let it foam.
Stir the foaming mixture into the flour mixture.
Add molasses and mix until stiff.
Bake
Pour the batter into a buttered pan.
Smooth the top with a spoon dipped in hot water.
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 main structure and the characteristic dense, earthy crumb.
- Wheat flour
- Adds gluten so the batter holds together better than rye alone.
- Sour milk
- Its acidity reacts with the baking soda to produce gas that lifts the cake.
- Baking soda
- Reacts with the acidic sour milk to release carbon dioxide for rising.
- Molasses
- Adds sweetness, moisture, and deep color and flavor to the cake.
The step that matters
Let the milk and baking soda foam before mixing. The foaming shows the acid and soda are reacting and releasing gas. Adding this mixture to the flour right away keeps that gas in the batter, so the cake rises properly.
