Smoothie Mason Jar

A Mason jar is a molded glass jar used in home canning to preserve food; while the bands are reusable, the lids are intended for single use when canning. By using a mason jar as the container, you’ll be able to freeze your spinach, kale, and celery green smoothie so you can have one later on in the week! Also, mason jars are durable. So use can reuse them over and over again. A Mason jar is a molded glass jar used in home canning to preserve food; while the bands are reusable, the lids are intended for single use when canning. By using a mason jar as the container, you’ll be able to freeze your spinach, kale, and celery green smoothie so you can have one later on in the week!
