Why it works: Wheat and rye match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 404 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Rye Bread
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
In a bowl, stir enough wheat flour into the warm water to make a batter for griddle cakes.
Add the homemade yeast and let it rise overnight.
Mix and rise
In the morning, pour the sponge into a mixing pan with the rye flour.
Dissolve the baking soda in lukewarm water and add it along with the salt.
Mix into a smooth dough, adding warm water if necessary.
Knead the dough well, cover it, and let it rise in a warm place for about 3 hours.
Knead again and shape into 4 medium-sized loaves.
Bake
Bake in a preheated oven at 400°F (200°C) for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye flour
- Forms the main dough structure and gives the loaf its characteristic dense, earthy crumb.
- Homemade yeast
- Ferments the sponge, producing gas that makes the dough rise.
- Wheat flour
- Forms the starter batter with the water, providing gluten to help the sponge hold its gas.
- Baking soda
- Reacts with acidity in the dough to produce carbon dioxide, adding lift.
The step that matters
Mixing the dough to a smooth consistency. Rye flour absorbs water differently from wheat and has weaker gluten, so the dough can be too stiff or too sticky. Adding warm water only as needed keeps hydration right, and thorough kneading develops what gluten there is for a well-risen loaf.
