Sprout safety — read first
Raw sprouts are nutritious but carry a real risk: the same warm, damp conditions that sprout a seed can also grow harmful bacteria. Use seed sold specifically for sprouting, keep your jar and hands clean, rinse and drain twice a day, refrigerate after harvest, and throw out any batch that smells musty or off or turns slimy. If you are pregnant, very young, older, or immune-compromised, cook sprouts thoroughly or skip them raw.
How to grow it
- Rinse 1 tbsp of sprouting broccoli seed, then soak overnight in cool water in a jar.
- Drain fully and rest the jar tilted mouth-down so water escapes and air circulates.
- Rinse and drain twice a day, keeping the seeds damp but never sitting in water.
- When tails are 1–2 inches (day 3–5), set in indirect light for a few hours to green up, then refrigerate.
Common mistakes
- Water pooling at the bottom (turns sour)
- Skipping a rinse, especially in warm weather
Pro tip
A final few hours of indirect light greens them and lifts their compound content.
