carrageen (Chondrus crispus)
- Carrageen is also known as Irish moss or carrageen moss.
- Carageen is an Atlantic seaweed. The word carageen comes from the Irish carraigin meaning "little rock".
- You would not probably want to eat this raw, but rather to create a thickening agent to use in much the same way that you might use agar agar.
- Industrially it is harvested along with other seaweeds, to create the food thickenening and stabilizing agent E407 or E407a.
- It is also used in brewing, for fining beer and wines.
