Heat a heavy bottom wok or pan on medium high heat. Add half a teaspoon of amaranth seeds in it and stir until they start popping.
Once the half teaspoon seeds popped, remove from wok and start adding a tablespoon amaranth seeds at a time and let the pop while continuously stirring.
If the first trial batch doesn't pop wait until you get the right heated temperature of the wok and do not add more. Keep trying adding only a tiny amount of seeds until the pan is heated enough.
Likewise, pop all the amaranth and place in a big mixing bowl.
Sieve the seeds using a strainer to remove the unpopped ones.
Meanwhile into the same wok add chopped jaggery and a tablespoon water. Let it melt and make a one stirring consistency syrup.
Add the jaggery syrup into the sieved amaranth seeds and mix well.
Wet your palms and start making round balls, keep applying water on your palms before start making each ladoo.
Store in airtight container and enjoy.
Notes
Be patient a=while popping the amaranth seeds and add a tablespoon at a time only.
