Why it works: Buttermilk and flour are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Steamed Brown Bread
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Mix the batter
In a bowl, beat molasses and shortening together.
Add buttermilk, baking soda, and salt; mix well.
Stir in Indian meal, graham flour, and wheat flour until combined.
Steam and brown
Pour the mixture into a steamer and steam for 1 hour.
Transfer to a hot oven at 400°F (200°C) for 10-15 minutes until browned.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds sweetness, dark colour and a moist, dense crumb.
- Buttermilk
- Adds moisture and acidity that reacts with the baking soda.
- Baking soda
- Reacts with the acidic buttermilk to produce gas that lightens the bread.
- Indian meal
- Gives the bread its coarse, grainy texture and structure.
- Graham flour
- Adds a nutty, coarse texture and helps give the loaf body.
- Wheat flour
- Provides gluten and structure to hold the loaf together.
The step that matters
Transfer to a hot oven until browned. Steaming sets the loaf but leaves it pale and soft. A short blast of dry heat browns the surface, and leaving it too long can dry or harden the crust.
