To make Irish Moss Paste:
1. Soak 1/2 cup of dry moss in lukewarm water for a few minutes, then rinse to clean from salt and sand. Work with your hands through the moss and clean from dirt, pebbles, blue rope pieces (leftover from harvest) and soak again in fresh water, make sure you have plenty of water to cover and choose a bigger bowl, because the moss will expand.
If you are short on time, use warm or lukewarm water to soften the moss faster.If you have time, you can also put it into the refrigerator over night and continue next day.
2. At the next rinse check again on dirt or any brown parts, rinse very well. Soak again.
3. When the moss has become white, soft yellow color, multiplied its volume and got soft, it is ready to process it to paste. Blend 1 1/2 cups well hydrated (soaked) moss with 3/4 cup water in a high speed blender.
4. 1 cup dry moss will yield 3 cups soaked moss. You might have plenty. Store the Irish Moss paste in a clean glass container (Mason jar, etc) in the refrigerator.
Irish moss paste will last in the refrigerator for a at least 14 days, most of the time 3 weeks. If you have to much moss prepared you may also use the ice cube tray and fill it with Irish Moss Paste and freeze, you have perfect portions you can work with.
