Irish moss is a type of seaweed. It grows in cold water and is used in recipes for added nutrition and thickening properties It carries no colour and relatively no taste while providing a lot of fibre, protein, trace minerals and nutrients. Raw foodists love Irish moss for its use as a thickener, so it is a great addition to a raw vegan diet. In the kitchen, Irish moss can be used any time you want something smooth, thick or creamy – for example, to make desserts, thicken a sauce or soup and make extra-creamy mashed potatoes.
