There's a certain je ne sais quoi about dumplings. I'm fascinated by dumplings of all cultures, shapes, and forms. From matzoh balls to pierogi, from momos to gnocchi, they are the perfect comfort food.
The fact that they are usually a hundred percent carbohydrate is completely irrelevant.
What you need:
2 lbs sweet potatoes, roasted (45 minutes in a 450 degree oven), peeled, mashed well
2/3 cup ricotta cheese (throw it in a fine sieve to allow water to drain out, a couple of hours or so)
1.5 cups or more of all purpose flour
salt and pepper to taste
The idea is to make a dough out of the above, using as little flour as possible. To make that possible, use the firmest variety of sweet potatoes you can find. Roast them in the oven instead of boiling. Dust all surfaces with generous amounts of flour and keep dusting.
Bring a huge pot of water to a boil.
Mix together the mashed sweet potatoes, ricotta, flour, salt and pepper. Don't overwork the dough. All you want is for it to stay together and not stick to your hands. Divide the dough into six pieces (a dough separator/scraper comes in very handy.)
Roll each piece out into a half-inch thick string and cut into gnocchi a bit larger than your thumbnail. Then press a floured fork into the back of the gnocchi to create grooves for sauce. Go here for a technique video.
Cook the gnocchi in three batches. Simply add them to the boiling water and fish out with a slotted spoon as soon as they start to float. Place in a platter.
At this point, you can spread them on a sheet, freeze, then store the frozen pieces in a ziplock bag. Or you can saute them in a sauce of your choosing. I melted a couple of tbsp of butter, fried ten sage leaves in it and added 2 tbsp of maple syrup, before giving the gnocchi a quick saute. Delicious.
