Why it works: Rye and wheat 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 ↓
Bohemian Rye Bread
Ingredients
Directions
Prepare the sponge
Dissolve one yeast cake in ½ cup of warm milk with a little sugar.
Sift together 2 pounds of rye flour and 1 pound of wheat flour.
Heat 1 pint of milk and 1 pint of water.
Add the raised yeast and enough flour to make a sponge.
Set the sponge in a warm place until full of bubbles.
Make and shape the dough
Add 1 tablespoon of salt, a little caraway seed, and enough flour to make a stiff dough.
Turn the dough out onto a floured board and knead well.
Set aside in a warm place to rise until doubled in size.
Form the dough into loaves or one large round loaf and let it rise again.
Bake
Brush the top with beaten egg.
Bake small loaves for 1 hour and large loaves for 1 hour and 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye flour
- Provides the dense, earthy structure characteristic of rye bread.
- Wheat flour
- Adds gluten to give the dough more elasticity and lift than rye alone.
- Yeast (in the method)
- Produces carbon dioxide that makes the sponge and dough rise.
- Milk
- Adds richness and softness to the crumb and helps browning on the crust.
The step that matters
Let the sponge become full of bubbles before adding the salt and remaining flour. Fermenting the sponge first lets the yeast get active before salt slows it down, so the dough rises well and develops flavor.
Swap the caraway
How well each one fits the dish's main ingredients (milk, sugar, rye, flour, wheat, egg):
- Cinnamonfits better
- Carawaythe original
- Nutmegfits about as well
- Turmericfits less well
Fit is the average pairing score against milk, sugar, rye, flour, wheat, egg. Candidates are from the same food group and used in at least 100 recipes.
