Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Peach Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make a rich biscuit crust using Lewis Condensed Baking Powder.
Roll the crust thick and place it around the pie dish.
Layer peaches in the dish, adding butter, sugar, and a little flour between layers.
Continue layering peaches until the dish is full.
Cover with a thick crust and cut a slit in the center.
Pour a little water into the slit.
Bake in a moderate oven at 350°F (175°C) until golden.
