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 ↓
Stuffed Potatoes
Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the potatoes
Bake the potatoes until done and hot.
Cut a small piece from one end of each potato and scoop out the inside, leaving the skin unbroken.
Fill and finish
Mash the potato well and season with plenty of butter, salt, and pepper.
Return the mashed potato to the skins, leaving it protruding about 1 inch.
Set the potato on the opposite end, crushing it slightly to make it stand firmly.
Roughen the exposed potato with a knife or fork.
Place the potatoes in a very hot oven at 400°F (200°C) to lightly brown the tops.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy flesh that is mashed and piped back into the skins as the filling.
- Butter
- Adds fat and richness, making the mashed potato smooth and moist.
The step that matters
Roughen the exposed potato before browning. Scoring or roughening the mashed surface creates more exposed edges and peaks, which brown faster and more deeply in the hot oven. A smooth surface stays pale.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatothe original
- Carrotfits less well
- Onionfits less well
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
