For those who don't know, sea moss (also called Irish moss) is used to make drinks in the Caribbean. I haven't tried it yet, but I've always been curious. It's available bottled at many Caribbean groceries and restaurants, but you can make your own with this recipe.
If you're interested in learning more about sea moss farms, I found this video about a sea moss cultivation project in St. Andrew, Grenada. It's a very interesting process.
