Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

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.
Cut cold boiled potatoes into slices ¼ inch thick.
Sprinkle with salt and pepper.
Spread with butter and sprinkle with sugar.
Place in a 400°F (200°C) oven to brown.
