To remove the vein with the shell still on, make a cut along the back of the shrimp with kitchen shears. Gently remove the vein.
Storage: Once your shrimp are peeled, rinsed, and dried off, put in an airtight container in the refrigerator for 1-2 days until you are ready to use.
Freeze: Cover a baking sheet with parchment paper. Place rinsed and dried peeled shrimp on the baking sheet in a single layer. Freeze, then transfer to a freezer bag for up to 6 months.
