Ingredients

Directions

The book says “a moderately slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, mix the graham flour, wheat flour, salt, and baking soda.

  3. In another bowl, combine the sour milk and molasses, stirring until smooth.

Mix and bake

  1. Add the wet ingredients to the dry ingredients and mix well.

  2. Fold in the broken walnuts.

  3. Pour the batter into a greased bread pan.

  4. Bake for 1 hour.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.

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 acidic sour milk to produce gas, which lifts the batter.
Sour milk
Its acidity activates the baking soda and adds tang and tenderness to the crumb.
Graham flour
Provides the bulk and the coarse, brown, slightly nutty structure of the loaf.
Wheat flour
Adds gluten-forming protein that gives the loaf structure alongside the graham flour.
New orleans molasses
Adds sweetness, dark colour, moisture and a deep flavour to the brown bread.
Broken walnuts
Add crunch and a rich, toasty flavour throughout the loaf.

The step that matters

Mixing the wet and dry ingredients. Mix just until combined. Overmixing develops too much gluten in the flour, making the bread tough and dense, while the baking soda's lift begins as soon as it meets the acidic milk.

Swap the walnut

How well each one fits the dish's main ingredients (flour, wheat, milk, molasses):

  1. Almondfits about as well
  2. Flaxseedfits about as well
  3. Walnutthe original
  4. Beansfits about as well

Fit is the average pairing score against flour, wheat, milk, molasses. Candidates are from the same food group and used in at least 100 recipes.
