Why it works: Rye and corn work together. They rank in the top 7% of all ingredient pairs, and cooks put them together in 182 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Dissolve the baking soda in the sour milk.
Combine all ingredients in a mixing bowl.
Pour the mixture into a greased loaf pan.
Steam and bake
Steam for four hours.
Bake in a preheated oven at 350°F (175°C) for twenty minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn meal
- Provides the bulk and coarse, crumbly texture of the bread.
- Rye meal
- Adds an earthy flavor and a denser, moister crumb than wheat flour gives.
- Sour milk
- Supplies moisture and acidity that reacts with the baking soda.
- Molasses
- Adds sweetness, moisture and the dark color of the loaf.
- Baking soda
- Reacts with the acid in the sour milk to release gas, helping the bread rise.
The step that matters
Dissolve the baking soda in the sour milk first. Baking soda must be fully dissolved before mixing so it spreads evenly through the batter. Undissolved pockets react unevenly, leaving some areas bitter, soapy or uneven in rise.
“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.
