if the ham is cooked
simply slice it thinly for your sandwich
then a brief soak in ice water them pat dry
5 - 10 minutes or less
I do this all the time w my SV commercially corned beef after SV
and freezing
I use ice water to keep the fat firm. salt will come out based on surface area
it doesnt take long and the taste improves to the taste of
Ham , Beef , w/o the salt burn.
