Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. In a large bowl, mix the Indian meal and rye flour.

  2. Add the pumpkin puree, warm water, yeast, molasses, salt, and baking soda.

  3. Stir until the mixture is very stiff.

Shape and rise

  1. Divide the batter into two well-buttered iron or earthen pans.

  2. Wet your hands with cold water and smooth the top of the batter.

  3. Let it rise until it has doubled in size.

Bake

  1. Bake in a hot oven at 400°F (200°C) until cooked through.

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

What each ingredient does

Indian meal
Provides the main body and coarse, crumbly texture of the loaf.
Rye flour
Adds structure and a dense, slightly tangy character to the bread.
Yeast
Produces gas that makes the stiff batter rise and become lighter.
Baking soda
Reacts with acidic molasses to release gas, helping the loaf rise and lighten.
Molasses
Adds sweetness, dark color, and moisture while contributing to the bread's flavor.
Pumpkin puree
Adds moisture and softness to the batter.

The step that matters

Let it rise until it has doubled in size. Yeast gas and baking soda lift the stiff batter. If it rises too little, the loaf bakes dense and heavy; the batter should expand fully before it goes into the oven.

Swap the pumpkin

How well each one fits the dish's main ingredients (rye, flour, corn, molasses):

  1. Raisinfits better
  2. Figfits better
  3. Vanillafits better
  4. Pumpkinthe original

Fit is the average pairing score against rye, flour, corn, molasses. Candidates are from the same food group and used in at least 100 recipes.
