Gelatin

Gelatin comes in two forms: powder and sheet. I prefer using gelatin sheets as it is more manageable. Gelatin is extracted from the collagen found inside an animal’s skin and bones, and is made of protein. It melts when heated and solidifies when cool. Some fruit such as pineapple and kiwi contain an enzyme which breaks down protein, thus causing gelatin to lose its gelling abilities. I prefer using gelatin that contains 2–3 per cent moisture. Check the label on the packaging.
