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
Preheat the oven to 350°F (175°C).
In a bowl, combine the rye flour and wheat flour.
Make the batter
Add the sour milk and baking soda; stir until foaming.
Mix in the coarse sea salt and molasses until stiff.
Bake
Transfer the mixture to 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 dense, earthy character of the cake.
- Wheat flour
- Adds gluten for more elastic structure, helping the cake hold together with the rye.
- 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, causing the batter to rise and foam.
- Molasses
- Adds sweetness, moisture, and a deep color and flavor that supports browning.
The step that matters
Add the sour milk and baking soda. The baking soda must react with the acidic sour milk right away, while the mixture foams. Waiting too long lets the gas escape before baking, which leaves the cake flat and dense.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
