Blanch 400 grams of cleaned and washed spinach leaves and drain all the water. Use a sieve to ensure the water drains out as much as possible. Allow it to cool completely. Squeeze out the excess water using your hands. Ensure you squeeze out all of the remaining water.
Transfer this to the small jar (chutney jar) of a mixer grinder. Add 2 teaspoons of water and blend into a coarse paste. Set aside.
Heat oil in a Kadai. Add cumin seeds and let them splutter. Add green chillies and saute for 30 seconds.
Add blended spinach and sauté for 2-3 minutes. Add cardamom powder and salt and mix well
Add gram flour and corn flour and mix well. Cook for a minute. Turn off the heat and set it aside.
To make the paneer filling, combine grated paneer, salt, pepper, cardamom powder and fresh cream in a bowl. Mix well and set aside.
To make the koftas, divide the paneer mix into four and shape them into balls. Divide the spinach mix into four and set aside. Take one part of the spinach mixture and flatten it on your palm.
Place one paneer ball in the middle and enclose it with the spinach mix. Roll it between your palms to form a smooth round ball. Ensure there are no gaps or holes as this will cause it to break or make the oil seep in.
Repeat with the remaining spinach and paneer mix till you have four big kofta balls.
Coat the koftas in cornflour. Dust off any extras and set them aside.
Heat oil in a kadai for deep frying to medium-high. Carefully drop the koftas into the kadai and cook on a medium flame for 4-5 minutes.
Remove from the oil and transfer to a tissue paper-lined plate. Cut each kofta in half and you'll see how they look like shaam savera.
Reheat the gravy if necessary and transfer to a serving bowl or platter. Place the halved koftas on top of the prepared gravy. Serve immediately!
