A rich, deeply spiced curry slow-cooked until the aromatic tomato and onion reduction clings intimately to the tender cuts.
Brown the onion in oil, add the ginger-garlic paste, chili powder, and garam masala, then add the minced mutton and salt and cook until dark, dry, and fragrant.
Heat a paratha on the tawa, pour half the beaten egg over one side, and flip briefly so it sets into a coating.
Place a line of the bhuna mutton filling on the egg side, add a few sliced onions, and roll the paratha tightly.
Wrap each roll in butter paper so it holds its shape, halve it, and serve hot kati-roll style.
