Why it works: Potato and butter are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Potato Chips
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.
Prepare
Wash and peel the potatoes, then cut them into very thin slices.
Place the slices on a cloth and drain thoroughly to absorb all moisture.
Prepare a well-buttered paper bag and add the potato slices.
Close the bag and fasten the end with clips.
Bake and serve
Place the bag on a grid shelf in a hot oven at 400°F (200°C).
Cook for about 15 minutes, turning the bag once or twice.
Open the bag, season the chips with fine salt, and serve.

What each ingredient does
- Potatoes
- Provide the starchy slices that crisp and brown as their moisture evaporates in the oven.
- Butter
- Adds fat that helps the chips brown and gives them a richer flavour.
The step that matters
Drain the potato slices thoroughly. Surface moisture must be removed before baking, because water on the slices delays browning and crisping and can leave the chips soft instead of crisp.
