Why it works: Potato and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 8,303 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
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.
Bake the potatoes
Bake equal-sized potatoes in a 400 °F (200 °C) oven until tender, about 1 hour.
Cut off a small piece from each baked potato and scoop out the inside, leaving the skin unbroken.
Fill and finish
Mash the scooped potato and mix in plenty of butter, pepper, and coarse sea salt.
Return the mashed potato to the skin, allowing it to protrude about 1 inch above the skin.
Use a fork or knife to roughen the top of the potato.
Place the filled potatoes back in the oven for 1 minute to color the tops.

What each ingredient does
- Potatoes
- Form the crisp skin shell and the fluffy mashed filling inside.
- Butter
- Adds fat and richness, making the mashed filling smooth and flavourful.
The step that matters
Returning the filled potatoes to the oven for 1 minute. Only one minute is stated, so the tops can easily burn or stay pale. Browning depends on surface heat and sugars, and the short time is meant to colour the tops without drying the filling.
