The Buckwheat Groats, of course, should be uncooked. If the groats are a medium brown colour, they have been toasted and won’t sprout.
To grow Buckwheat Sprouts:
Soak hulled buckwheat seed for 20 minutes, no longer.
Drain off the soaking water, and rinse the groats until the rinse water is clear (they will give off a good deal of starch.)
Drain thoroughly (they will have absorbed all the water they need.)
Set out at room temperature, but not in direct sunlight.
They will sprout in 1 to 1 1/2 days.
Store in refrigerator.
