Why it works: Flour and walnut are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 5,873 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Walnut Bread
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Combine flour, salt, baking powder, and chopped walnuts in a bowl.
Add milk and a well-beaten egg to the dry ingredients and mix until combined.
Let the mixture rise in pans for 20 minutes.
Bake in a preheated oven at 400°F (200°C) for 45 minutes, placing the pans in a water bath.
Cover the bread for the first 15 minutes of baking.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
