I cooled, peeled, and chopped them so they would fit in my stand mixer's cheese grater.
I don't own a potato ricer as suggested in the original recipe plus that requires a little more muscle.
Using the largest grater attachement gave me the 'riced like' potatoes I was looking for
When you contrast the russets with the purple potatoes you can really see the difference.
The kids integrated the remaining ingredients using a potato masher
Using my hands I rolled the dough into a ball (it would be so much nicer if it had been all purple potatoes, since the white potoatoes made the dough a muddy color
I divided the dough into four and rolled it into 1/2-inch thick tubes and used a fork to mark them with the classic gnocchi dents
I cut them into segments and lightly dusted them with flour so they didn't stick together
The kids and husband enjoyed them (and the kids loved to help make them). A nice alternative to plain pasta. I don't know that I would make them all the time because they are a lot of work and make a pretty big mess, but as a special treat it was definitely doable.
