- Begin by popping open the amaranth seeds first. To do this, heat a pan with a glass lid on medium heat. Throw in a few seeds to check for the right temperature.  
- Once it's reached the right temperature for popping, work in batches, adding one tablespoon at a time, and pop the amaranth seeds. Transfer them out into a bowl when they stop popping. Keep an eye on the ones you add because they have a tendency to burn. 
- Next, break the piloncillo bars into the same saucepan, add the honey and water and warm the mixture, stirring, until fully dissolved. Set aside to cool. 
- Add the pop amaranth to the syrup and stir until all the amaranth seeds are covered. 
- Oil a baking tray add the amaranth/syrup mixture and press down with a rolling pin until evenly spread in the tray.  
- Leave it to cool for a couple of hours. Once hardened cut into whatever shapes you like and serve
