Gelatin is available in the market both in the powdered form and in sheet form. Pigskin gives gelatin with each processing, but the highest quality of gelatin is one that is obtained with first time processing of pigskin. This gelatin has a great gelling capacity and is almost clear. It also has a mild flavor.

At rest, it is able to just hold itself together as a solid, but given a spin in the blender (or in your mouth), it flows more freely.
