In growing Buckwheat Sprouts, you need to use hulled buckwheat (aka Buckwheat Groats) as the starting seed. Otherwise, if you use unhulled, the very tough seedcase will be on the sprout.
The Buckwheat Groats, of course, should be uncooked. If the groats are a medium brown colour, they have been toasted and won’t sprout.
Cooking Tips
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 ½ days.
Storage Hints
Store in refrigerator.
