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.

Mix the batter

  1. In a large bowl, combine graham flour, rye flour, wheat flour, cornmeal, molasses, salt, and baking powder.

  2. Add enough water or milk to form a soft dough.

Bake

  1. Transfer the dough to a greased loaf pan.

  2. Bake in a cool oven at 300°F (150°C) for 4 hours.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Graham flour
Provides the bulk structure and the hearty, whole-grain body of the loaf.
Molasses
Adds moisture, dark color, and a sweet, deep flavor.
Baking powder
Releases gas to lift the dough so the loaf rises as it bakes.
Cornmeal
Adds a coarser texture and a slightly grainy crumb.

The step that matters

Bake low and slow in a cool oven. Long, gentle heat sets the dense crumb through without over-browning the outside. A hotter oven would set the crust before the interior cooks, leaving the loaf gummy or cracked.
