Idaho® Potato Knishes

[SanDiegoSunriser]

Although this is a very creative video, it moves way too fast. Closeup shots are needed...And what is "rice potatoes?"

How is that done? What device is used? And the final scene on folding the knish, how is that done? A closeup, more slow shot would help.

@SanDiegoSunriser A potato ricer is a pretty common cooking implement.  You can fing it at any culinary store. Got mine on Ebay pretty cheap
