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 meaty body and savory flavor of the hash.
- Potatoes
- Supply starch and bulk, giving the hash its soft, cohesive texture.
- Butter
- Adds fat for richness and helps the hash brown in the pan.
- Milk or cream
- Adds moisture and richness so the hash stays tender rather than dry.
The step that matters
Adding the milk or cream. Too little liquid leaves the hash dry and crumbly, while too much makes it soggy. Add just enough to moisten the mixture, so the potatoes and beef stay tender and hold together as they heat.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beef, potato, butter, pepper, milk):
- Capsicumfits about as well
- Onionthe original
- Tomatofits about as well
- Carrotfits about as well
Fit is the average pairing score against beef, potato, butter, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
