While I was shopping for seeds for the garden, I came across a few seeds for sprouting. My favourite is alfalfa but I had to settle for broccoli and some mustard seeds. I started with the broccoli and it took about 5 - 6 days. Many of the seeds didn't sprout. I have no idea if that is normal but it made for an expensive bit of sprouts. It made about a pint and cost about $2.50.
Simply cut a piece of cheesecloth to fit the top of a jar and use the metal ring to hold it in place. Rinse the seeds twice a day until they are the size you want.
Drain all the water and leave the jar upside down, slightly atilt so any residual water can drain.
