You will need instant Clear Jell for making the instant pudding mixes. There is regular Clear Jell, which is for cooking, and the instant Clear Jell. You order it online. I normally get it from
www.barryfarm.com, but there are other places,too.
One site also has recipes for using it. Not sure if it Barry Farm,too, or not.
Clear Jell is a modified cornstarch. It is the same type of thickener used in the commercial food industry. The cooked makes great pie fillings,too.
The Clear jell will not break down when frozen,either, like regular cornstarch.
