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 ↓
Boston Brown Bread, III
Ingredients
Directions
Mix and pour
Combine Indian meal, rye flour, wheat flour, molasses, milk, salt, and baking soda in a bowl.
Pour the mixture into a long tin pail.
Steam
Place the pail in a pot with enough water to keep it boiling.
Cover the pail tightly to ensure it is water tight.
Boil for three hours to achieve a crustless loaf.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Indian meal
- Provides the bulk and coarse, grainy texture of the loaf.
- Rye flour
- Adds structure and a dense, hearty crumb with its own flavour.
- Wheat flour
- Contributes gluten for some structure and a lighter crumb.
- Molasses
- Adds sweetness, moisture and the dark colour of the loaf.
- Baking soda
- Reacts with the molasses acidity to lift and lighten the batter.
The step that matters
Cover the pail tightly. A loose lid lets steam escape and water seep in, so the bread can turn soggy or dry unevenly. A tight seal keeps the moisture steady while the loaf steams through.
“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.
