Matzoh Meal Kleis

From 1918:

Beat one tablespoon of chicken schmalz till quite white; pour one cup of boiling water over one egg. Add it to the dripping; stir these together, then add the flour, seasoning, a little chopped parsley, ginger, pepper and salt,
and enough matzoh 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.
