Line a small baking sheet with several layers of paper towels.
Place 8 eggs in a pan of cold water over high heat. Bring the water to a boil and cook for 4 minutes. Immediately plunge eggs in ice water to stop cooking process. Gently peel eggs once cooled.
Combine ground fish (see note if using gefilte fish), salmon, 2 egg yolks, horseradish, chives, parsley, salt and pepper and 3 tablespoons matzo meal. ( I recommend cooking a teaspoon of this mixture in a pan to check the seasoning.) The fish mixture will be sticky and that is good!
Place potato starch in a small bowl and place egg whites in a small bowl. And finally place 1 cup of matzo meal in a small bowl.
Wrap the fish mixture around a peeled hardboiled egg, until it completely covers all sides of the egg. Dredge covered egg in potato starch, then egg white and then matzo meal. Continue with remaining eggs.
Pour evoo in a saucepan and place over medium-high heat. Once a deep fry thermometer registers 360°F. Fry eggs, a few at a time, until brown and crispy all around.
Transfer eggs to lined sheet and sprinkle with kosher or sea salt. Serve eggs as soon as possible with Horseradish Sauce for dipping.
