Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Underdone mutton
- Provides the main meat, sliced thin so it warms through quickly in the gravy.
- Gravy from gristles and trimmings
- Supplies moisture and savory flavor that keeps the sliced meat tender.
- Onion
- Adds aromatic flavor to the gravy.
The step that matters
Let it soak until thoroughly warm, but do not let it boil.. Boiling toughens meat proteins and makes them stringy and dry. Gentle heat lets the slices warm through while staying tender and juicy.
