Why it works: Milk and wheat are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,418 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. 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.
Make and steam the batter
Mix the sour milk, sweet milk, molasses, cornmeal, wheat flour, currants, salt, and baking soda well.
Grease Boston brown bread tins or baking tins and fill each about halfway.
Steam for 2 hours.
Finish and serve
Place in a 400°F (200°C) oven for 5 minutes before removing from the tins.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baking soda
- Reacts with the sour milk to produce gas, lifting and lightening the batter.
- Sour milk
- Its acidity activates the baking soda and adds tang and moisture.
- Yellow cornmeal
- Provides the bulk and coarse, hearty structure of the bread.
- Wheat flour
- Adds gluten-based structure that helps hold the loaf together.
- Molasses
- Adds sweetness, dark colour and moisture to the bread.
The step that matters
Fill the tins only about halfway. The batter rises as the baking soda reacts and the steam expands the crumb. Overfilling can cause it to overflow or turn dense when the tins can't hold the rise.
Swap the currant
How well each one fits the dish's main ingredients (milk, molasses, wheat, flour):
- Raisinfits better
- Vanillafits better
- Figfits better
- Currantthe original
Fit is the average pairing score against milk, molasses, wheat, flour. Candidates are from the same food group and used in at least 100 recipes.
