Boston Corn Bread

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Mix and rise

  1. Combine sweet milk, sour milk, molasses, wheat flour, corn meal, and salt in a bowl.

  2. Add enough water to wet the mixture without making it a batter, stirring constantly.

  3. Mix in the yeast and make the mixture as stiff as possible with a spoon.

  4. Let the mixture rise overnight in a warm place.

Add soda and pan

  1. In the morning, add 1 teaspoon of baking soda dissolved in a little water.

  2. Transfer the mixture to a large pan and smooth the top with a wet hand.

  3. Let it stand for a short time before baking.

Bake

  1. Bake for 5 to 6 hours at 300°F (150°C). If baking late in the day, let it remain in the oven overnight.

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

What each ingredient does

Corn meal
Forms the main body and crumb of the bread.
Yeast
Produces gas during the overnight rise, lightening the mixture.
Sour milk
Its acidity reacts with the baking soda to add lift and tang.
Baking soda (in the method)
Reacts with the acid in sour milk to release gas and aid rising.
Molasses
Adds sweetness, moisture, and a deep brown color.
Wheat flour
Adds gluten-based structure that helps hold the loaf together.

The step that matters

Adding the baking soda in the morning. Baking soda reacts quickly with the acid in sour milk, releasing gas. Once dissolved, it should be mixed in promptly and not left to sit, or much of its lifting power is lost before baking.
