Place the broccoli sprouting seeds in a wide-mouth mason jar and cover with a few inches of filtered water.
Put a sprouting lid on and place the jar in a slightly warm, dark place away from direct sunlight for 8-12 hours.
The next day (or at least 8 hours later), drain off the water and rinse with fresh water.
Rest the mason jar upside down at an angle on a sprouting jar holder or inside a bowl so any remaining water can drain. Continue to keep the jar in a slightly warm but mostly dark place during this time.
Rinse the sprouts 2-3 times a day and place them back on the jar holder or bowl after each rinse. I rinse at meal times so I remember. After a few days, all the seeds should start to break open and grow.
Keep up with the rinsing and keep the seeds in a darkish place until the raw sprouts are about an inch long. At this point they can tolerate some indirect sunlight or low light exposure.
Eat the seeds once you see some dark green leaves, usually 3-4 days after they start to sprout.
Notes
This whole process usually takes about a week. I start a new batch every 1-2 days so we have a constant supply.
