Take chenna in a wide plate or paraat.
Start mashing chenna using the base of your palm.
Mash until chenna turns creamy. It may take 5 to 6 minutes.
Transfer this creamy chenna in a bowl carrying wet ingredients.
Mix very well.
Spread pistachios at the base of the greased baking tin. You need to spread pistachios on a side which will be the top as per your cake tin.
Transfer this batter in it and level it.
Bake in preheated oven @170°C for 60 to 70 minutes in the middle rack with both rods on.
Take it out and check the done-ness by inserting a toothpick. If it comes out clean, its a sign that chenna Poda is baked perfectly. And if it doesn't happen, you need to bake for more time.
Let it cool down before inverting.
Cut into slices and enjoy.
