Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

Sift the baking powder into the flour and mix in the dry ingredients.
Combine the dry mixture with the milk and add the salt.
Let the mixture stand for twenty minutes to rise.

Bake

Bake in a slow oven at 300°F (150°C) for 45 minutes.

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

What each ingredient does

Flour: Provides the structure that holds the loaf together as it bakes.
Baking powder: Releases gas during baking, lifting the batter so the bread rises.
Milk: Hydrates the flour and adds moisture and tenderness to the crumb.
Walnut meats: Add fat, texture and a nutty flavour to the finished bread.
