Walnut Loaf

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.

Make the batter

  1. In a bowl, mix together the eggs, sugar, and milk.

  2. Add the flour, baking powder, and salt, and mix until combined.

  3. Fold in the walnuts.

Rise and bake

  1. Let the mixture rise in the pan for 15 minutes.

  2. Bake in a preheated oven at 350°F (175°C) for 45 minutes.

Finish

  1. After baking, roll the loaf in a damp towel.

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

What each ingredient does

Flour
Forms the gluten network that gives the loaf its structure.
Eggs
Add structure and richness, helping the loaf hold together as it bakes.
Milk
Adds moisture and helps the batter come together.
Sugar
Adds sweetness and helps the crumb brown lightly in the oven.
Baking powder
Releases gas during baking, lifting the loaf and giving it a lighter crumb.
Walnuts
Add texture and a nutty flavour throughout the loaf.

The step that matters

Mix only until the flour is combined. Once flour is wet, gluten develops with each stir. Overmixing after adding the flour makes the loaf tough and dense, so stop as soon as no dry flour remains.

Swap the walnut

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

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

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