Why it works: Sweet potato and flour work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 627 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sweet Potatoes
Ingredients
Directions
The book says “a moderately hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Boil sweet potatoes until done.
Skin and slice them lengthwise into thin slices.
Place slices in a baking pan.
Sprinkle with flour.
Add enough butter and sugar to make a syrup.
Bake in the oven at 400°F (200°C) until light brown.
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.
