Why it works: Beef and potato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 2,052 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Corned Beef Hash
Ingredients
Directions
Cook the hash
In an iron frying pan, combine the butter, chopped beef, chopped potatoes, water, and pepper.
Stir gently to mix, being careful not to break the potato pieces.
Cover the pan and heat until thoroughly warmed.
Remove the cover and move the hash to one side of the pan, allowing it to reach the top.
Keep this side on the hottest part of the stove until browned.
Serve
Use a knife to loosen the hash, then place a platter on the pan and turn it upside down to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, helping the hash brown and carrying flavour.
- Chopped beef
- Provides the savoury, meaty body of the hash.
- Chopped potatoes
- Supply starch and bulk, becoming tender inside and crisping on the browned side.
- Water
- Adds moisture that helps the potatoes soften while the pan is covered.
The step that matters
Keep the hash on the hottest part of the stove until browned. Potato starch and meat proteins brown only with sustained direct heat and little moisture. Turning or moving the hash too early leaves it soft and pale instead of forming a crisp crust.
Swap the potato
How well each one fits the dish's main ingredients (butter, beef, pepper):
- Potatothe original
- Onionfits about as well
- Capsicumfits about as well
- Tomatofits less well
Fit is the average pairing score against butter, beef, pepper. Candidates are from the same food group and used in at least 100 recipes.
