Should kale be stored in a closed plastic bag in refrigerator?

Yes, kale should be stored in a closed plastic bag in the refrigerator to maintain its freshness. The bag helps retain moisture while preventing excess humidity, which can lead to wilting or spoilage. It's best to leave some air in the bag to allow for ventilation. Additionally, washing kale before storing can lead to faster decay, so it's advisable to wash it just before use.
