Step 1

Soak the seeds. Pour the broccoli seeds into a jar and fill halfway with fresh cool water. Place to one side out of direct sunlight to soak for 6-12 hours (according to the packet instructions). This is the only time the broccoli seeds should sit in water. Sitting in water is a common cause of spoiling. If they spoil, discard them and begin again.

Step 2

Rinse and drain regularly. Securing the lid with your fingers, empty the soak water from the jar, then fill halfway again with fresh cool water. Swirl the seeds around for a few moments before pouring the water away. Be sure to drain the soak water away thoroughly. Place the jar at an angle in a bowl to allow any excess water to escape. Rinse and drain twice daily until ready. I like to do this in the morning and the evening.

Step 3

When ready. The sprouts are ready to harvest in about five days. They'll have grown 2-5 centimetres long and developed their first tiny green leaves. Place them somewhere bright for a few hours so the leaves can photosynthesise and turn green. Rinse and drain one last time. Remove them from the jar and set them out to dry on some paper towel before storing.
