bowl    with    a   rubber
spatula,    cream   the butter
and sea salt    on  medium
speed   for about   60
seconds.    DO  NOT WHIP—
this    would   incorporate
too much    air into    the
butter. Air bubbles make
the final   dough   puff    when
you bake    it. They    also
make    the dough   porous,
which   would   allow
moisture    from    the filling
