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

Preheat the oven to 400°F (200°C).
In a bowl, combine sour milk, oatmeal, white flour, sugar, baking soda, and salt, then mix until well combined.

Bake and serve

Pour the batter into a greased baking dish.
Bake in the preheated oven until golden brown.
Serve hot.

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

What each ingredient does

Sour milk: Adds moisture and acidity, which reacts with the baking soda to help the bread rise.
Oatmeal: Adds a hearty, chewy texture and absorbs liquid from the batter.
White flour: Provides the structure that holds the loaf together as it bakes.
Baking soda: Reacts with the acid in the sour milk to produce gas that lifts the batter.
Sugar: Adds a little sweetness and helps the crust brown during baking.
