Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Mix and rise

  1. In a large bowl, combine Indian meal, rye meal, molasses, vinegar, salt, and baking soda.

  2. Gradually add lukewarm water and mix until well combined.

  3. Pour the mixture into a greased baking dish.

  4. Cover and let it rise for about 1 hour.

Bake

  1. Preheat the oven to 350°F (175°C).

  2. Bake for 5 hours until firm and cooked through.

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

What each ingredient does

Indian meal
Forms the main body of the bread, giving it a coarse, sturdy crumb.
Rye meal
Adds a dense, hearty texture and a deeper, earthy flavour.
Molasses
Adds sweetness, dark colour and moisture to the loaf.
Baking soda
Reacts with the acid in the batter to release gas, helping the bread rise.
Vinegar
Provides the acid that activates the baking soda.

The step that matters

Bake until firm and cooked through. This batter is dense and wet, so it needs a long bake to set fully in the centre. Pulling it early leaves a gummy, undercooked crumb.
