Why it works: Rye and flour match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,320 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, mix the rye flour, cornmeal, Graham flour, molasses or brown sugar, salt, and homemade yeast.
Add warm water to form a stiff dough that can be stirred with a spoon.
Let the dough rise for several hours or overnight.
Bake
When the dough is light, add the dissolved baking soda and beat well.
Turn the mixture into well-greased deep bread pans and let it rise again.
Bake in a moderate oven at 350°F (175°C) for 3 to 4 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornmeal
- Gives the loaf its coarse, crumbly texture and characteristic grainy body.
- Rye flour
- Adds flavour and a dense, moist crumb through its gluten-poor structure.
- Homemade yeast
- Produces gas that makes the dough light before baking.
- Baking soda
- Reacts with the molasses or sugar acids to add extra lift and darken the crumb.
- Molasses or brown sugar
- Adds sweetness, moisture and a deep brown colour.
The step that matters
Adding the baking soda after the dough rises. The dough must be light before the dissolved baking soda goes in, so the extra lift is added to an already risen dough. Beating it in well distributes the soda evenly so the loaf does not have pockets or a bitter patch.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
