Graham Gems

Oven, in the book's wordsA quick oven

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

  1. Preheat the oven to 400°F (200°C).

Make the batter

  1. In a bowl, beat the egg and mix in the sugar until well combined.

  2. Add the sour milk, graham flour, baking soda, and salt, then stir until smooth.

Bake

  1. Pour the batter into hot gem pans.

  2. Bake in the preheated oven until golden brown.

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

What each ingredient does

Egg
Binds the batter and adds structure and moisture as it sets in the oven.
Sour milk
Its acidity reacts with the baking soda to lift the batter and tenderize the crumb.
Graham flour
Provides the main structure of the gems and a nutty, wholesome flavor.
Baking soda
Reacts with the acid in the sour milk to produce gas that makes the gems rise.
Sugar
Adds sweetness and helps the crust brown during baking.

The step that matters

Pour the batter into hot gem pans. A preheated pan starts cooking the batter the moment it touches the metal, setting the outside quickly and helping the gems rise and form crisp, browned edges instead of spreading or sticking.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
