Apple Gems

Oven, in the book's wordsA moderate oven

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
Provide moisture, tartness, and body to the batter.
Beaten egg
Binds the batter and helps give the gems structure as they set.
Molasses
Adds sweetness, moisture, and a deep colour that helps browning.
Cornmeal
Gives the gems their coarse, crumbly texture and structure.
Sifted flour
Provides structure so the batter holds its shape when baked.
Magic soda
Leavens the batter so the gems rise and turn out lighter.

The step that matters

Dissolving the Magic Soda and thinning the batter. The soda is the leavener, so it must be evenly dissolved and mixed through the batter. Too little water leaves the batter stiff and uneven, while the rising begins as soon as the soda meets the acidic ingredients, so the batter should go into the pans promptly.

Swap the apple

How well each one fits the dish's main ingredients (egg, molasses, flour, butter):

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits better
  4. Applethe original

Fit is the average pairing score against egg, molasses, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
