Step #3 Boil the potatoes for about 20 mins in salted water until tender.
Step #4 Pass potatoes through the fine disk of a potato ricer, & cool.
Step #5 Pour the potato onto the counter, & begin to mix in the flour.
Step #6 Add a pinch of salt & gather into a dough.
Step #7 Cut the dough into 4 pieces, & roll this into finger-thick logs.
Step #8 Cut each log into 1" pieces, & press each over the reversed tines of a fork (the resulting ridges allow the gnocchi to grab onto the sauce later).
Step #9 Now dust a tray with four & line the gnocchi in a single layer on top of it.
Step #10 Set aside, & bring a large pot of salted water to a boil.
Step #11 Once boiling, drop in the gnocchi, & remove them with a slotted spoon when they rise to the surface (this means they are ready).
Step #12 Meanwhile, crumble the Gorgonzola into chunks, & melt in a pan over medium-low heat with the butter & cream.
Step #13 When ready, sprinkle with the Parmigiano, mix the gnocchi & the sauce, & serve.
