Instructions
Method 1. Store the fresh cilantro in a glass of water.
Fill a large mason jar or other glass container with approximately 1 to 2 inches of cool water. Place the bunch in the glass with the stems down, in the cold water like a bouquet of flowers.
Next loosely cover the leaves with an upside-down plastic bag. You can seal the bag around the herb using a rubber band if you wish.
Store this jar of cilantro in the fridge. Making sure to check the water every now and then. Change the water if you notice it is looking cloudy.
Method 2. Plastic bag and paper towels.
Separate the cilantro and lay it in a single layer on 1 to 2 layers of paper towels. You can also use a flour sack towel for this.
Roll up the towel up like a jelly roll, loosely so you don’t damage the leaves.
Place this in an airtight container or a plastic bag that can be sealed.
