Ingredients

Directions

The book says “a quick 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).

Make and bake

  1. In a large bowl, mix the rye meal, flour, molasses, egg, salt, sour milk, and baking soda until well combined.

  2. Drop spoonfuls of the mixture onto a greased baking sheet.

  3. Bake for 15-20 minutes or until golden brown.

Serve

  1. Let cool before serving.

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

What each ingredient does

Rye meal
Gives the biscuits their dense, hearty texture and a distinctive earthy flavour.
All-purpose flour
Provides gluten structure so the biscuits hold their shape while baking.
Molasses
Adds sweetness and depth, and contributes to the browning of the crust.
Egg
Binds the dough and adds structure and richness.
Sour milk
Adds moisture and acidity that reacts with the baking soda.
Baking soda
Reacts with the acidic sour milk and molasses to produce carbon dioxide, helping the biscuits rise.

The step that matters

Baking until golden brown. Baking soda reacts quickly with the acidic sour milk, so the batter should go into the oven promptly once mixed. Pulling the biscuits when golden brown, rather than earlier, lets the starches set and the crust form so they hold their shape.
