Put a cup of einkorn berries in a quart mason jar. Fill the jar with filtered water and cover with a mesh lid.
Keep it on the counter for 8 hours or overnight. You won't see any activity at the end of 8 hours. Drain the water (that's why a mesh lid is so convenient), rinse the grains with fresh water.
Discard the water again, tilt the jar to the side taking care to leave half the screen exposed, for air to circulate. Leave it in a warm place for 1 to 3 days, changing the water twice a day. The grains should stay moist but not submerged in water.
The sprouting will start in 12 to 24 hours after the end of your first soak. Once tiny tails start showing - the grains are done. You don't want to let the sprouts to get too long.
Rinse the grains again and drain well. Then dry them in a dehydrator, or spread them on a cookie sheet lined with parchment paper and bake at the lowest oven temperature until dry, about 3 hours.
