Amaranth is a seed that is eaten as a grain. The Aztecs knew about it and frequently prepared it. Amaranth can be found at many health food stores. This seed is gluten free like corn, and just like corn, it can be popped in a similar fashion. After you pop your amaranth, you can use it as you would popcorn, or eat it as a grain. See References.
Place the skillet on the stove over high heat. Let the skillet become hot enough that a drop of water disappears when you drop it on the surface.
Put a spoonful of amaranth into the skillet.
Shake the skillet or stir the seeds until all of the amaranth has popped. This will take about 15 - 20 seconds per spoonful.
Remove the popped seeds from the skillet and repeat with the remaining amaranth. You will have about 2 cups of popped seeds. Use in any recipe requiring popped amaranth. See Resources.
