Wash the spinach in a colander or a salad spinner and make sure to get rid of as much water as possible.
Place a clean kitchen towel completely open on a flat surface. Spread the leaves on the towel.
Pat the spinach dry with a piece of unbleached and fragrance-free paper towel, or using another kitchen towel on top.
Store them as the last ingredient of your batch cooking to ensure they are completely dry.
Storage option 1: Ziplock bag. Place the spinach in a ziplock bag where you are going to add one or two unbleached and fragrance-free kitchen paper to absorb any humidity. While sealing the bag, eliminate as much air as possible.
Storage option 2: Glass container. The best storage option is to use a glass container and alternate a few layers of spinach with kitchen paper.
