I decided to give this a try to see how it would work out. It was a complete success and so I am writing down the recipe to keep for future reference.
4 Large sweet potatoes
2 Cups grated parmesan cheese
Potato Flour or Potato Starch
1/2 Tbsp Butter or margarine
Salt and Pepper to taste.
Boil the sweet potatoes until soft.
Strain out the water and using a potato press, puree the sweet potatoes*.
* sweet potatoes absorb more of the water than potatoes do. Before mashing the potatoes, squeeze the press gently to squeeze out the excess water, then mash the potatoes into a bowl.
Add the egg, butter, salt and pepper to the potatoes. Also add about half the quantity of potatoes of flour, and mix.
The overall dough should be light, and still slightly sticky but not too much so.
roll out the dough on a floured surface and cut and mould into appropriate sized shapes. Some recipes also recommend putting the dough in a piping bag and sniping off pieces of dough as it comes out of the bag.
Add the gnocchi to salted boiling water and boil until they start to float.
Serve warms with butter and salt, or sauce of some kind.
Sauce recommendations: The sauce from the previous recipe (the goulash stew creation), Alfredo sauce, or Mushroom sauce.
Tips: Do not add too much flour since the result will be too heavy. If you are worried, boil a small amount of dough to see how it tastes before deciding whether to add more flour.
If you run out of potato flour, you can add normal flour. Too much normal flour however will weigh down the gnocchi.
If you are feeling experimental, you can try different cheeses. One option is to substitute the parmesan with cottage cheese (drained) and add nutmeg and cinnamon then serve with butter and sugar.
