OK, so I grew some grain amaranth. I wanted to hurry up and harvest the seeds, before a million seeds got spread all over my yard.
So I just cut off the dry seed heads and rubbed them around in my very small mesh strainer with a bowl under it. That works very nicely for basil, the little black seeds come through and very little else. Worked out not as well with the amaranth. What I got was the tiny black seeds, plus a lot of small brown pieces and a few small green pieces. I think the brown/green is pieces of the seed pods.
So now what do I do? I think I could separate the seeds, by putting a small amount of the mixture at a time on a piece of paper and tilting it back and forth. The seeds are round and heavier and they tend to separate and roll off the paper leaving the chaff behind. But it would be time-consuming and I think I would end up with a few tablespoons of seeds.
Other people that have grown amaranth?
If I do separate it out and get my tablespoons of amaranth seeds, what do I do with them?
