This is a quick recipe (5 minutes maximum from start
to finish)) that will yield a similar finish though it
is not strictly the classic 'Mornay''
Scallops should be very lightly cooked, if allowed to
over cook they
will toughen and become rubbery. At point #5 they should
still only be half cooked as they will finish cooking
in the sauce. This comes with practice, but better to
err on the side of caution rather than over cook them.
The dish may also be finished by placing it in the serving
dish, sprinkling with a little grated cheese and/or breadcrumbs
and browning under the salamander (grill). As this will
further cook the scallops, extra care must be taken.
Adding a mild (English) mustard to these recipes yields
a sauce/dish called Thermidor.
Both Mornay and Thermidor are also excellent with other
seafoods: crab, crayfish, etc and exactly the same process
is followed.
