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 ↓

Ingredients
Directions
The book says “a fairly hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Sift together the rye flour, wheat flour, and cornmeal.
Add salt, brown sugar, and baking powder to the flour mixture.
Rub the boiled potatoes through a sieve, diluting with water until cool.
Mix the potato mixture into the flour until it forms a batter.
Steam and bake
Pour the batter into a well‑greased covered mold.
Simmer the mold in a saucepan half full of boiling water for 1 hour.
Remove the mold, uncover it, and bake in a 400°F (200°C) oven for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye flour
- Gives the bread its dark color and distinctive earthy flavor.
- Wheat flour
- Provides the gluten-based structure that holds the loaf together.
- Cornmeal
- Adds coarse texture and a golden crumb to the loaf.
- Boiled potatoes
- Add moisture and starch, keeping the crumb soft and tender.
- Baking powder
- Releases gas to lift the batter so the loaf rises.
The step that matters
Pour the batter into a well-greased covered mold. The batter is loose and wet, so a well-greased mold lets the loaf release cleanly, and a tightly covered mold traps steam so the bread cooks through moist instead of drying out during the long simmer.
Swap the potato
How well each one fits the dish's main ingredients (rye, flour, wheat, sugar):
- Beetrootfits better
- Arrowrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against rye, flour, wheat, sugar. Candidates are from the same food group and used in at least 100 recipes.
