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 ↓

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, mix the white cornmeal, yellow cornmeal, graham flour, and salt.
Add the boiling water to the dry ingredients and mix well.
In another bowl, combine the sweet milk and molasses, then add to the scalded meal mixture.
Dissolve the baking soda in the sour milk and add it last to the mixture.

Steam and bake

Pour the batter into a covered cylindrical mold or a covered pail.
Steam the mixture for 3 hours, then uncover and bake in a 350°F (175°C) oven for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

White cornmeal: Provides the bulk and coarse, hearty texture of the bread.
Yellow cornmeal: Adds structure and a light corn flavour to the crumb.
Graham flour: Adds body and a nutty, slightly sweet wholegrain flavour.
Molasses: Adds sweetness, moisture and the dark colour typical of the bread.
Baking soda: Reacts with the acidic sour milk to produce gas that lightens the batter.
Milk: Moistens the dry meal and helps hydrate the cornmeal into a batter.

The step that matters

Adding the baking soda. Baking soda needs an acid, such as sour milk, to react and release gas. Dissolving it in sweet milk without acid would leave it unactivated and the bread would rise poorly.
