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 ↓
Hickory Nut Macaroons
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Pound the hickory nut meats finely.
Add ground spice to the nuts.
Prepare frosting as you would for cakes and stir it into the nut and spice mixture until it's easy to handle.
Flour your hands and shape the mixture into marble-sized balls.
Place the balls on buttered baking sheets, leaving space for them to spread.
Bake in a 400°F (200°C) oven.
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.
