Moisture migration.

Moisture leaves the cells of the food and condenses elsewhere, either
on the inside of the package, if wrapped, or on the walls of the
freezer or on the special coils in frost-free freezers that are
designed for the purpose.

As moisture either evaporates or sublimes from the surface, the
remaining moisture in the food tries to equalize and moves towards the
surface. That movement can be very slow in a conventional freezer that
isn't opened much to much faster in a frost-free that raises and
lowers the temperature often.

That lost moisture can't really be replaced by any soaking or cooking
techniques to reconstitute the food to anything approaching its
original texture and flavor.
