Peel and cut the tapioca into medium sized pieces
Wash thoroughly and cook by adding turmeric powder and enough water
When the kappa is 3/4th cooked add salt and cook well
Then drain them and mash the cooked kappa well using a ladle and keep aside
Cut the beef into very small pieces ..Wash well with vinegar and salt
Marinate the beef with salt,vinegar,chilly powder,coriander powder,ginger-garlic and curry leaves for minimum half an hour
Then add this marinated beef to a cooker and cook till done
The time is depending up on the beef
For me its only took 1 whistle and 10 more minutes ..U can knw by pressing the piece
So keep that cooked beef aside
Now take a non stick pan ,heat 3 tbsp of coconut oil
Add curry leaves ,saute well ,then add sliced onion ,ginger ,garlic and green chilly
Saute till the onion becomes light brown in colour
Then add chilly powder and garam masala in low flame ..Saute until the raw smell goes
Then add cooked beef and boil well ..Now add our mashed kappa and mix well..Finally add pepper powder ..Stir well
Check the salt ..Add if needed..Finally add boiled egg cut into 4 to 5 pieces ..(opt)
So the yummy Kappa Biriyani is ready..The hotness of chilly powder varies..so add chilly according to ur taste
U can substitute prawns ,chicken instead of beef
