Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stuffed Potatoes
Ingredients
Directions
Prepare the potatoes
Bake the potatoes until done.
Cut the potatoes in half and scoop out the insides without breaking the skins.
Fill and bake
In a bowl, mix the scooped potato, chopped onion, beaten egg, butter, cream or milk, and salt until light.
Stuff the mixture back into the potato skins.
Brush the tops with the yolk of the egg.
Return to the oven to brown and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base that is scooped out, mashed and refilled into the shells.
- Egg
- Binds the filling so it holds its shape when stuffed back into the skins.
- Butter
- Adds fat and richness, softening the filling's texture and flavour.
- Cream or milk
- Adds moisture, keeping the mashed filling smooth and light.
- Onion
- Adds aromatic savoury flavour to the filling.
The step that matters
Scooping without breaking the skins. Thin potato skins tear easily when scooped; a torn shell cannot hold the filling. Leaving a sturdy wall of potato keeps the shells intact for stuffing.
Swap the onion
