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. In a bowl, mix the Graham flour, wheat flour, and salt.

Make the batter

  1. Dissolve the baking soda in a little warm water and stir it into the flour mixture.

  2. Add the sour milk and mix well.

  3. Beat the mixture hard until smooth.

Bake

  1. Pour the batter into small gem pans.

  2. Bake for 45 minutes or until golden brown.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Graham flour
Provides the coarse, nutty body that gives the gems their characteristic texture.
Wheat flour
Adds gluten structure so the batter holds its shape while baking.
Sour milk
Its acidity reacts with the baking soda to produce gas, helping the gems rise.
Baking soda
Reacts with the acid in sour milk to release carbon dioxide, leavening the batter.

The step that matters

Beat the mixture hard until smooth. Thorough mixing develops gluten in the wheat flour, giving structure. Mix the baking soda in before the batter sits, since the acid-soda reaction starts immediately and gas escapes if the batter waits.
