Step 1: Marinate the Mutton
In a large bowl, combine mutton, curd, ginger paste, garlic paste, red chilli powder, white pepper powder, turmeric, and salt.
Mix thoroughly until every piece is coated.
Cover and refrigerate for at least 2 hours. Overnight marination delivers the best flavour.
Step 2: Prepare Fried Onions
Heat ghee in a heavy pan.
Fry sliced onions until golden brown and crisp.
Remove and drain on absorbent paper.
Set aside.
Step 3: Cook the Mutton
Heat ghee in a handi.
Add bay leaves, cardamoms, cloves, and cinnamon.
Allow the spices to release their aroma.
Add sliced onions and sauté until lightly golden.
Add marinated mutton.
Cook over medium heat for 10 minutes.
Reduce the flame and continue cooking until the mutton becomes tender.
Add a little hot water if necessary.
The gravy should be thick and cling to the meat.
Step 4: Prepare the Saffron Infusion
Soak saffron strands in warm milk.
Allow the saffron to release its colour and aroma for 15 minutes.
Step 5: Cook the Rice
Wash basmati rice gently until the water runs clear.
Soak for 30 minutes.
Bring water to a boil.
Add whole spices and salt.
Add soaked rice.
Cook until approximately 70 percent done.
Drain immediately.
The grains should still have a slight bite in the centre.
Step 6: Begin Layering
Spread the cooked mutton evenly in the handi.
Place a layer of partially cooked rice over the mutton.
Sprinkle fried onions.
Add mint and coriander leaves.
Drizzle saffron milk.
Add kewra water and rose water.
Repeat if making multiple layers.
Step 7: Seal for Dum
Cover the handi with a tight-fitting lid.
Seal the edges using wheat flour dough.
Place the handi over a tawa on low heat.
Cook on dum for 30 minutes.
Step 8: Rest Before Serving
Switch off the flame.
Allow the biryani to rest undisturbed for 15 minutes before opening.
This resting period allows the flavours to settle beautifully.
