China grass or Agar Agar or Kanten is a sea weed and completely vegetarian. It gives a smooth, glossy finish and many chefs prefer to use it over gelatin. China grass, if used properly sets easily at room temperature. The method of using Agar Agar or Gelatin (which is derived from the collagen inside animals’ skin and bones) may be the same. We must be careful to follow the recipe correctly to get the desired texture.
