Ingredients

Directions

The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Mix the flour and meals together in a large bowl.

  2. Add 1 pail of water and mix well.

  3. Stir in the salt and another pail of water.

  4. Add the molasses and mix until combined.

  5. Incorporate the baking soda and yeast, adding the last pail of water gradually as needed.

Bake

  1. Pour the mixture into a greased baking pan.

  2. Bake in a cool oven at 300°F (150°C) for 6 to 7 hours, or steam if preferred.

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

What each ingredient does

Indian meal
Provides the bulk and coarse, hearty texture of the loaf.
Rye meal
Adds a dense, earthy flavour and body to the crumb.
Molasses
Adds sweetness, dark colour and moisture, and helps the loaf brown.
Baking soda
Reacts with the acidic molasses to lift and lighten the bread.
Yeast
Ferments the sugars to add flavour and some rise to the batter.
Strong flour
Adds gluten structure to help hold the loaf together.

The step that matters

Incorporate the baking soda and yeast, adding the last pail of water gradually as needed.. Baking soda reacts quickly with the acid in molasses, so it should be mixed in evenly and the batter should not be left to stand. Adding water gradually keeps the batter at a pourable, consistent texture so the loaf rises and bakes evenly.
