Amaranth

I've not grown amaranth but have grown quinoa which is similar. I grew it last year in with the squash and pumpkins with some sweetcorn. It looks very like a large version of fat hen and needed supporting with canes. When cooking, it has a bitter coating that you should wash off first (quinoa at any rate). I give it a good rinse and at the same time get rid of a lot of the chaff that didn't 'winnow' out. I also give a rinse with hot water after cooking to remove any bitterness.
