Why it works: Wheat and corn match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 465 recipes. Both carry hexanal, which smells green, grassy. The science ↓
Boston Brown Bread
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
In a large bowl, combine the wheat flour, corn meal, and Graham flour.
Add the molasses, baking soda, salt, lard, sour milk, and enough water to form a stiff sponge.
Pour the mixture into brown bread tins.
Steam and bake
Steam the tins for 2 hours.
Remove from the steamer and bake in a 350°F (175°C) oven for 10 minutes.
Serve
Take the bread out of the tins and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wheat flour
- Provides the main structure that holds the loaf together as it steams.
- Corn meal
- Adds a coarse, crumbly texture and a slightly gritty bite to the loaf.
- Graham flour
- Contributes a nutty flavour and a denser, more textured crumb.
- New orleans molasses
- Adds moisture, dark colour and a deep, sweet, slightly bitter flavour.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lightens the batter.
- Sour milk
- Its acidity activates the baking soda and tenderises the crumb while adding moisture.
The step that matters
Keeping the tins covered and steaming gently. Steam cooks the batter slowly and keeps it moist; if water boils dry or the tins are left uncovered, the loaf dries out and may not set evenly through the centre.
