Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Chop the sour apples very fine.

Make the batter

  1. Stir the chopped apples into a bowl with the beaten egg, molasses, cornmeal, and sifted flour.

  2. Dissolve the Magic Soda in warm water and add it to the mixture, using enough water to thin the batter.

Bake

  1. Pour the batter into buttered gem pans.

  2. Bake in the preheated oven until golden.

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

What each ingredient does

Sour apples
Add moisture and a tart flavour that balances the sweet molasses.
Beaten egg
Binds the batter and helps the gems hold their shape as they set.
Molasses
Adds sweetness, dark colour and a rich flavour to the batter.
Cornmeal
Provides the coarse, crumbly texture that gives the gems their structure.
Sifted flour
Provides structure so the batter sets into a firm, light crumb.
Magic soda
Reacts with the acidic apples and molasses to help the gems rise.

The step that matters

Dissolving the Magic Soda in warm water. Soda must be fully dissolved and evenly mixed so it reacts throughout the batter; lumps can leave bitter patches and uneven rising. Thin the batter only enough to pour, since too much water weakens the structure.

Swap the apple
