Using as little as 0.5 ounces (15 grams) of dried sea moss will make about 17 fluid ounce (500 ml) of sea moss gel. Making your own gel is a simple process which has a few basic steps that I’ll outline for you. However, if you would rather buy your Sea Moss Gel pre-made, then you have plenty of options to choose from.
Step 1: Cleaning
First, rinse your sea moss thoroughly with cool, clean water. You need to make sure you remove any sand, salt, and foreign matter off the seaweed.
Step 2: Soaking
Once you are happy with the cleanliness of the seaweed, soak the it in about 17 fluid ounce (500 ml) of clean, filtered water for 24 to 48 hours.
Some people suggest a shorter time frame and and boiling the sea moss. But I think it’s better to soak it for a longer period of time, and not cook it.
Keep in mind that this will expand to about three times its original size. It will be quite soft and slimy to touch (depending upon the species).
Step 3: Blending
Blend the sea moss with roughly 200ml of fresh water. It should start to take on a smooth consistency. The more liquid you add the runnier the consistency.
Step 4: Storing
Decant the sea moss gel into a clean glass container and store in the fridge until ready for use. This will last for between two and three weeks before it will begin to smell funny.
If you find that your gel is thicker than you would like, you can add more water even after it has set to thin it down. it may take a few batches until you figure out what consistency you like the most.
