"Instant puddings have as one of their ingredients pre-gelatinised starch which makes them an "add milk and sitr" commodity.

Gelatinized starch is a pre-cooked starch that is used as a thickener. After cooking the liquid mixture of starch, fluid and additives it is dried into a powder. When a liquid is added to this pre-gelatinized starch, as in an instant pudding mix, it re-forms into the thickened consistency of a cooked starch.

Pre-gelatinised/pre-gelatinized/gelatinised/gelatinised starches eg corn, wheat, maize, potato are usually found commercially. If you can find a source, you would then have to find and adapt a commecial recipe or adapt one of you own. "
