What is sea moss?

Sea moss is a sea vegetable similar to seaweed. Also known as Irish moss or Chondrus Crispus, it forms a thick gel when soaked or boiled, and it's packed with nutrients. This gel is the base for this punch and is also used in smoothies, vegan desserts, and sauces. Look for wildcrafted or wild-harvested sea moss for the best quality.
