Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix the rye meal, salt, and baking soda.
In another bowl, beat the egg yolks until pale and creamy.
In a separate bowl, beat the egg whites until stiff peaks form.
Combine the beaten yolks with the egg whites.
Make the batter
Make a well in the dry ingredients and add the sour milk.
Mix vigorously until the batter is light and effervescent.
Bake
Grease twelve small cake tins and fill them two-thirds full with the batter.
Bake for 20 minutes without opening the oven, then check for doneness.
Bake for up to 45 minutes, ensuring they are thoroughly cooked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye meal
- Provides the structure and earthy flavour of the cakes.
- Eggs
- Whipped whites lighten the batter, while yolks add richness and help set the crumb.
- Baking soda
- Reacts with the sour milk to produce gas that makes the cakes rise.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tang.
The step that matters
Mix vigorously after adding the sour milk. Vigorous mixing develops the batter's airy, effervescent texture. Once the baking soda reacts with the acid in the sour milk, the gas bubbles begin forming, so the batter should be mixed and baked promptly to keep the rise.
