Shred the zucchini and place it in a large mixing bowl.  Stir in 1 teaspoon Salt.  Set aside for 10 minutes.

After this time, use your hands to squeeze as much liquid as possible out of the zucchini.  Then place the zucchini in a large mixing bowl.

Then stir in the flour, eggs, green onions, baking powder, remaining salt and pepper.

Preheat the Blackstone grill over medium high heat (approximately 350-400 degrees F).

Spread the vegetable oil out onto the Blackstone grill with a spatula.

Scoop the zucchini mixture onto the grill using a 1/4 cup measuring cup. Gently press the mixture down to flatten out the patties.

Cook each of the patties for 2-3 minutes until the fritter is browned.  Flip and cook the other side for 2-3 more minutes. Watch them closely as they cook so that they do not burn.

Remove from the grill and place on a plate lined with paper towels.

Continue this process until all the fritters are cooked.

Serve topped with the sour cream and enjoy!
