chemical    leavening,  or  some    combination of
these.  Russian blinis  sometimes   include beer,
which   may contribute  effervescence.  The
batter  is  poured  onto    the griddle and allowed
to  cook    until   bubbles begin   to  rise    and break
on  the upper   surface;    the cook    then    flips   the
cake    to  set the second  side    before  the
leavening   gas escapes.
Crumpets    are an  English invention,  small,
flat,   yeast-raised    cakes   with    a   distinctively
pale,   cratered    top surface.    They’re made    from
a   somewhat    thick   pancake batter  that’s
allowed to  become  bubbly  from    yeast   activity,
then    poured  into    ring    molds   to  a   depth   of
about   0.75    in/2    cm, cooked  very    slowly  until
bubbles break   and set on  the surface,    then
unmolded    and turned  to  cook    briefly on  the
hole-y  side.
