Rinse and pat dry the bone-in mutton pieces.
Place mutton, onion, garlic, ginger, bay leaves, salt, and pepper in a large pot.
Add water to cover the meat by two inches.
Bring to a boil over medium-high heat and skim off any foam.
Reduce heat to a gentle simmer and cover partially.
Cook for 2.5 to 3 hours until the meat is very tender.
Rest the pot for 10 minutes off the heat.
Serve the mutton with generous ladles of the golden broth.
Tip: Keep the simmer gentle the entire time for the most tender result.
