  • Flavour/texture: Onion 


1. Soak for 8 -12 hours in your sanitised sprouting jar.
2. Drain your soaked sprouts and rinse well. Carefully shake any excess water out of the jar. You want a fine coating of water on the seeds but no puddles.
3. Disperse the seeds as best you can around the wall of the jar. As your sprouts grow this will become more difficult but just do your best to spread them out and avoid blocking the mouth of the jar, Invert the jar and place on its stand so any excess water can freely drain out. Ensure air can get into the jar.
4. Rinse and drain at least twice a day, every day. Shake excess water out of the jar. Your sprouts should be almost dry before each rinsing.
5. Your sprouts are ready as soon as all the seeds have sprouted and have had an additional day or two to grow.
6. Leave for an additional few days and the sprouts will grow bigger
7. Once you are ready to harvest, give the sprouts a final rinse and drain.
8. Place the sprouts on a clean kitchen towel and let air dry. Alternatively give them a whirl in a salad spinner.
9. Refrigerate and ideally use within 3 days
