Which starch is better?

[snowbigman]

I'm making dextrin and have potato starch and corn starch. Which is better for dextrin and does it changes something?

[Crazy Swede]

Both works.

 Depends on the temp it’s cooked at and length of time).if I recall …150*~ 200* spread thin mixed 15min  intervals, for a hour or two cook time . 
yellow dextrin is not as binding as the more brown /tan stuff.

We use commercially produce corn starch or dextrin.

It works super.
