Here is the EASY way out. . .
Take a large jar (at least 8 pieces but I usually do 12). . . but first get your veggies ready; slice the carrots, beets and onions. Layer in a heavy stock pot, the beets (my Bubbe''s secret ingredient), slices of fish, onions, carrots and seasonings; repeat as many times as is necessary with EVERYTHING but the beets. Pour the liquid from the jar over the fish and then bring to a boil. Turn down as simmer for about 45 minutes. Cool, remove from liquid and serve.
This tastes ALMOST a good as the real thing. . . try it you''ll like it.
