After soaking, drain the water and rinse the watercress under cold running water to remove any remaining impurities.

Can I use a vegetable wash or soap to clean watercress?
While it may be tempting to use a vegetable wash or soap to clean watercress, it is generally not recommended.

How often should I wash watercress before eating it?

By storing watercress properly and washing it just before eating it, individuals can enjoy this nutritious leafy green at its best.
Can I eat watercress raw without washing it first?

By washing watercress thoroughly before eating it raw, individuals can help minimize this risk and enjoy the numerous health benefits of this nutritious leafy green.
In addition to washing watercress, it is also important to handle it safely to prevent cross-contamination.

By taking the time to properly wash and handle watercress, individuals can enjoy it raw with confidence, knowing that it has been safely prepared and is ready to eat.
Are there any special considerations for washing organic watercress?

In fact, organic watercress may be more prone to contamination due to the use of natural fertilizers and pest control methods. By washing organic watercress thoroughly, individuals can help minimize the risk of foodborne illness and enjoy the numerous health benefits of this nutritious leafy green.
In addition to washing organic watercress, it is also important to choose a reputable supplier that follows safe and sustainable growing practices.
