gelatine

The name of isinglass is connected to none other than sturgeons, fish from which the bladders were extracted in a particular way, to create this gelatinous food product used in all those confectionery preparations. In the present, however, what is called isinglass - which is generally sold in the form of sheets or even as powder - is actually now produced mostly from pig rind, as well as through the use of some bovine parts such as bones and cartilaginous tissues. In principle, isinglass is always wetted with cold water and, only after its volume has increased, is it used with hot water or other ingredients at a high temperature.
