Rye Gems

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

  1. Dissolve the Magic Soda in warm milk.

  2. Add a pinch of salt and the beaten eggs, mixing well.

  3. Stir in enough rye flour to create a thin batter.

Bake

  1. Pour the batter into greased gem pans.

  2. Bake in a preheated oven at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Magic soda
Reacts with the milk and batter to help the cakes rise and lighten.
Eggs
Bind the batter and add structure as they set in the oven.
Rye flour
Forms the main structure of the cakes, with a thin batter giving a light crumb.
Milk
Provides the liquid that hydrates the flour and carries the Magic Soda.

The step that matters

Pouring the batter into greased gem pans. Greasing the pans well helps the cakes release cleanly after baking. Because the batter is thin and the rise depends on the leavening, it should be baked promptly once mixed.
