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 ↓
Potato Bread
Ingredients
Directions
Boil
Place potatoes in cold water.
Cut a slice off the rose-end to improve mealiness.
Boil the potatoes until tender.
Add ½ cup of cold water a few minutes before they are done.
Drain the water.
Return the pot to the heat to dry the potatoes for a few minutes.
Sprinkle the potatoes with coarse sea salt.
Serve and use leftovers
Serve hot.
For leftovers, peel warm potatoes and set aside for breakfast.
Fry or bake
Slice and fry the potatoes with pepper and salt.
Place whole potatoes in the oven with butter until browned.
Alternatively, fry in a pan with butter, pepper, salt, and chopped onion, stirring constantly until nicely browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy body of the bread, becoming mealy when cooked and dried.
- Butter or dripping
- Adds fat that promotes browning and a rich flavor in the frying or baking.
- Chopped onion
- Adds sweetness and aroma as it softens and browns with the potatoes.
The step that matters
Drying the potatoes after draining. Returning the drained potatoes to the heat evaporates surface water, so they turn mealy rather than wet and gummy and brown better when fried.
Swap the onion
How well each one fits the dish's main ingredients (potato, butter, pepper):
