Soak the lentils in water for at least 12 hours.
Drain water from soaked dal and make a fine paste using little or no water.*
Beat the lentil paste and salt in a large bowl until the mixture is light and fluffy. To test if the mixture is ready, take a spoonful of the paste and drop it in a bowl of water. It is ready if it floats.
Fill a piping bag with the paste.
Sprinkle poppy seeds on a greased cookie sheet.
