I have added besan and roasted gram flour in equal amounts to bring out the crispness.
I have sauteed the beetroots and carrots to remove the rawness and to seal the flavor.
Add the koftas only before serving otherwise it becomes soggy.
The gravy for koftas are usually spicy so you can increase or decrease the spiciness accordingly to your need.
You can add little more cream if you want to reduce spiciness and increase creaminess.
