Making sea moss gel Is Easy. Just rinse the salt off of the dry sea moss under running cool water. Then soak the cleaned sea moss with a couple of cut lemons in spring water for 12-48 hours. Pour off the water and place the sea moss into a blender. Add more fresh spring water and blend until smooth. Next, pour into a jar with a lid and refrigerate. It will turn into a more gel-like texture as it sits. That’s it!! You now have fresh, powerhouse sea moss gel ready for consuming!
