    Dear all,

    I think that George may be on to something. If the "turbot" is arrowtooth flounder (which is marketed as turbot), that species caught off the Pacific coast often has myxosporidean parasites (as do some of our hake populations) and they turn to fish porridge when thawed and cooked due to the release of proteolytic enzymes from the tiny parasitic cysts.

    Other thoughts?

    Hi Nancy,

    Three possibilities came to mind on the problem this person encountered.
    There are no doubt more but these are the first that popped into my
    head.

    The most benign is perhaps what the fish were feeding on similar to cod
    in the summer months. The flesh looks okay but cooks up excessively
    watery/mushy. Little doubt this also occurs with flats.

    A second possibility (highest probability IMHO) is that the fish was
    over phosphated or otherwise treated. Turbot is now a fish that is
    commonly "refreshed" so over-treatment/over-soaking is well within the
    realm of possibilities.

    A third, perhaps longer shot, is the possibility that the fish sold as
    turbot was actually something else, possibly arrowtooth, a notoriously
    mushy species.

    Hope this is of some help.

    Subject: liquid fish?

    Hello to all:

    I recently fielded a call from someone who purchased turbot in a
    supermarket. He broiled the fish, lightly breaded, the next night for
    the typical time of 10 mins to the inch. The flesh appeared to have
    nice texture, but when he went to eat the fish, it totally disintegrated

    like liquid in his mouth.

    Upon returning to the supermarket to complain, he was told that the
    fish was supposed to be cooked the day it was bought.

    Beyond the obvious problem with the seafood counter staff at that
    establishment, my question to you is "What could cause that fish to
    go totally liquid like that?"

    I don't know if it was previously frozen and thawed.

    Any thoughts or insights would be appreciated.

    Thanks,
