Place a piece of parsnip, parsley root, small onion in food processor and process until smooth. Put fish in large wooden bowl. add processed parsnips etc, salt, 4 cups of sugar, and 8 beaten eggs. Hock until mixture coats blade, add some matzo meal and hock some more.. It is VERY important to hock at least 15 minutes. When water is boiling, wet hands with cold water. form one ball and slip it into the boiling water. If it breaks apart, add more matzo meal to wooden bowl and hock. Always make a test piece before adding all the fish to the water. THE BALLS MUST HOLD TOGETHER AND FLOAT IN THE WATER. Form balls and gently slip into boiling water. add more water as needed.
