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 ↓
Cobned Beef Hash
Ingredients
Directions
Prepare
Boil the corned beef until tender and chop it finely.
Chop the potatoes to be one-third more than the amount of meat.
Cook
Slice the onions and brown them in butter until tender.
Add the chopped meat and potatoes to the onions.
Season with coarse sea salt and black pepper, then add enough water to moisten.
For extra flavor, add the chopped red pepper if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corned beef
- Provides the main savory meat base and most of the hash's flavor.
- Potatoes
- Add starchy body and bulk that holds the hash together as it cooks.
- Onions
- Browning in butter adds sweetness and a deeper savory flavor.
- Butter
- Adds fat for browning the onions and enriches the overall flavor.
The step that matters
Season with coarse sea salt and black pepper, then add enough water to moisten.. Adding water gradually keeps the mixture moist without making it soggy, since too much liquid stops the potatoes and meat from browning.
