Mix all these ingredients well
Cook this mixture to dry out excess water
Place a non-stick pan on high flame and add 1 tablespoon of water
Once the water starts sizzling add the bottle gourd mixture
Cook the mixture for 5 minutes till it dries
Once the mixture has cooled, down kofta balls out of it - should make about 8 kofta balls
Cook the koftas in the appam maker (also known as appe/appa maker). Can be bought at most Indian grocery stores and also on Amazon
Place the appam maker on high flame
Put 1 tsp oil ina bowl and then add a drop of oil in 8 sections of the appam maker and allow it to heat up
Use a silicone brush to spread the oil
Once the appam maker is hot lower the flame and place the koftas in each oiled sections
You can use any remaining oil to brush the koftas
Cover the appam maker
Check every 2 mins to turn the koftas
The koftas are cooked once they turn golden brown on the outside
Turn off the flame and remove the koftas and place separately
