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

  3. 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.
