Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Steamed Boston Brown Bread
Ingredients
Directions
The book says “a good oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Sift together the cornmeal, white flour, and Graham flour in a bowl.
Pour the boiling water over the sifted flours.
In a separate bowl, dissolve the baking soda and salt in the warmed milk, then add the molasses.
Gradually pour the milk mixture into the flour mixture, beating hard for 10 minutes.
Pour the batter into a round mold with a closed top.
Steam and bake
Place the mold in a pot of boiling water and cook for 3 hours.
Remove the cover, place the mold in a shallow pan of hot water, and bake in a 350°F (175°C) oven for 30 minutes to dry out and brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yellow cornmeal
- Gives the bread its coarse texture and characteristic golden color.
- White flour
- Provides the gluten-based structure that holds the loaf together.
- Graham flour
- Adds a nutty flavor and denser, heartier texture to the crumb.
- Baking soda
- Reacts with the acidity of the molasses to lift and lighten the batter.
- Molasses
- Adds sweetness, dark color, and moisture, and contributes to browning.
- Milk
- Hydrates the flours and adds richness and tenderness to the crumb.
The step that matters
Beating the batter for 10 minutes. Vigorous beating develops gluten in the white flour, giving the loaf structure. Adding the milk gradually keeps the batter smooth and evenly mixed so lumps do not form.
