NOTE: DO NOT TAKE FISH OFF RACK JUST YET
Remove rack with fish intact and set over a baking sheet or cooling rack for approximately 1 hour until fish is cool
After fish is cool, you should be able to remove the fish without it flaking apart onto a serving dish.
Or if you don't intend to serve at once, place in a heavy zip lock bag and store in the fridge until ready to use.
Will keep for at least a week in the fridge and up to 6 months in the freezer.
