It is best to work fast, but calmly, before the hot powder loses its warmth and its ability to take the shape of the mould. If you are making indoris in larger quantities, make sure that you have someone to help out with the moulding. Serve warm or cool. When cool, store in airtight containers. Indoris will be soft to bite in when fresh and will get harder on the second day. They can be stored at room temperature for 3 days or can be kept in the refrigerator for weeks. To make the refrigerated ones softer, just warm them up in your microwave oven before serving.
