Potato Ricer Unit: Cooking

Although it looks like a giant garlic press and works the same way, this potato ricer was used to make mashed potatoes.  The boiled potato is forced through the mesh, and comes out the other side in tiny pieces.  Just add some butter and a dash of milk for perfectly smooth mashed potatoes every time!  Unfortunately, it was not as easy to use as it seems.

What other types of vegetables do you think could be mashed in the ricer?
