Remove the cottage cheese from the cloth and blend it for a few minutes in a blender to achieve a smooth texture.
In the meantime, combine sugar and water in a saucepan and bring to a boil to make a one string sugar syrup.
Next, add the blended cottage cheese and mix well for a few minutes while constantly stirring (around 7 to 8 minutes under medium flame).
Add the grated khova and vanilla essence when the mixture starts to get sticky and combine thoroughly.
Cook for another 1 or 2 minutes once the mixture begins to leave the pan side wall, then turn off the heat.
Allow the mixture to cool for a few minutes before shaping it into lemon-sized balls or smaller balls (depending on the size of your mould).
Use your choice of moulds to give the lemon-size sondesh balls the desired shape and design.
After giving the shape to the sondesh keep them in refrigerator for 15 to 20 minutes and later serve kora paker sondesh.
