Preheat your oven to 400 degrees. Use a fork to poke several holes into your sweet potato for venting, then bake for 45 minutes. Remove and allow the sweet potato to cool until comfortable to handle.
Bring a large pot of well salted water to boil.
Remove the flesh of the sweet potato and discard the skins. Place the flesh in a large mixing bowl and mash with a potato masher or ricer. Move the puree to a lightly floured work surface and form a well. (Mashed sweet potato volcano)
Combine salt, pepper, and 1 Cup of flour, then evenly spread the mixture over the sweet potato well. Crack egg into a small bowl and lightly beat. Add egg to center of well and slowly incorporate the ingredients with a fork.
Fold all ingredients into each other and lightly knead until a dough forms. Separate the dough into four equal balls. On a well floured surface, roll each ball out into snake about the width of a cork. Cut each snake into bite size pieces.
Using a gnocchi board (or the back of a fork) and your thumb, press and roll each piece to form a ridged texture
Work in batches to cook the gnocchi in the well salted boiling water. Each batch will take 2-3 minutes to complete cooking depending on the size of your dumplings. The gnocchi will float to the surface when they are done cooking.
Remove the gnocchi from the boiling water, plate, then drizzle with honey and sprinkle with blue cheese and walnuts.
