Walnut 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

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

  2. In a large bowl, mix together sugar, baking powder, and salt.

  3. Add the egg and milk (or milk and water) to the dry ingredients and mix well.

  4. Stir in the flour until combined, then fold in the rolled nuts.

  5. Let the mixture stand for 20 minutes to rise.

Bake

  1. Pour the batter into a greased loaf pan and bake for 30 minutes.

Milk and flour 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 powder
Releases gas in the batter, lifting it so the loaf rises instead of staying dense.
Flour
Forms the gluten and starch structure that holds the loaf together once baked.
Egg
Binds the batter and adds structure and richness as it sets in the oven.
Milk
Supplies the liquid that hydrates the flour and dissolves the sugar and leavening.
Sugar
Adds sweetness and helps the crumb brown lightly during baking.

The step that matters

Stir in the flour until combined, then fold in the rolled nuts. Overmixing once the flour is added develops too much gluten, which makes the loaf tough and dense. Mix only until no dry flour shows, then fold gently so the nuts distribute without extra toughening.

Swap the nuts

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

  1. Almondfits better
  2. Milletfits better
  3. Chestnutfits better
  4. Nutsthe original

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