In a food processor or blender combine the polenta, yolk, flour, salt and parmesan cheese to form a dough. Can also be made by hand, place the flour on a flat board, make a well in the middle and add the remaining ingredients, combine with your hands to form a dough.
Move the dough to a lightly floured flat surface and cut small amounts of dough to form ropes and cut into ¾ inch (2 cm) pieces, then slide each piece on a fork and squeeze a little (but not too hard). Sprinkle with a little bit of flour and toss, so they don't stick together. Let the gnocchi rest for 20 minutes before cooking.
Cook the gnocchi in a large pot of boiling salted water, when they float to the top they are done. Toss with your favourite sauce. Enjoy!
If you find the dough too sticky then add a little flour a little at a time. Dough can also be sticky if your house is very warm.
How to store polenta gnocchi
Raw uncooked gnocchi should be cooked right away or within a few hours. If you are not cooking right away, place on a floured baking sheet, cover with a towel and store in a dry place for a few hours. Cooked polenta gnocchi can be stored in an airtight container in the refrigerator for up to two days. If I have not already added a sauce to them, I drizzle them with olive oil before storing so they don’t stick. You can also freeze gnocchi which is best for longer storage. Place on a parchment paper lined baking sheet then flash freeze until frozen. Store in the freeze for up to three months then just add to boiling water from frozen adding a few minutes to the cooking time.
