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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Sift together the rye flour, wheat flour, cornmeal, salt, brown sugar, and baking powder.
Wash, peel, and boil the potatoes until tender.
Rub the boiled potatoes through a sieve and thin with nearly 1 pint of water to make the batter.
Pour the batter into well-greased molds with covers.
Steam and brown
Set the molds into hot water, filling to within 2 inches of the top, and boil for 2 hours.
Remove the molds from the water, uncover, and place in a 400°F (200°C) oven for 20 minutes to brown on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye flour
- Provides the dark, earthy flavour and a dense, moist crumb.
- Wheat flour
- Gives the loaf structure so it holds together after steaming.
- Cornmeal
- Adds bulk and a coarse, tender texture to the crumb.
- Baking powder
- Releases gas to lift the batter so the bread is not wholly dense.
- Potatoes
- Add starch and moisture, keeping the bread soft and moist.
The step that matters
Boiling the molds in water. The molds must stay submerged to the right level for the full two hours. Steam from the water cooks the bread gently and evenly; if the water boils dry or the level drops, the loaf dries out and bakes unevenly.
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.
