Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meat flavour and body of the hash.
- Potatoes
- Break down during stewing to add starch and thicken the hash.
- Butter
- Adds richness and fat that carries the savory flavour.
- Flour (in the method)
- Thickens the hash if it turns out thin.
The step that matters
Stewing the potatoes and onion. The potatoes must be fully covered and stewed until tender so they soften and release starch, which helps bind the hash. Too little water can scorch them.
Swap the summer savory
How well each one fits the dish's main ingredients (mutton, potato, onion, butter, pepper):
- Garlicfits better
