Beat chicken schmalz till quite white; pour boiling water over egg. Add it to the dripping; stir these together, then add the flour, seasoning, a little chopped parsley, ginger, pepper and salt, and enough matzoth meal to form into small balls the size of a marble. Drop these into the boiling soup and cook about fifteen minutes. Test one in boiling water and if it boils apart add more meal.
