Soaking first and repackaging would probably be better,then again,while salty....if you like salty its good.
Here's what I did to serve.Sliced,into a warm water bath about 15 minutes to heat and soak a bit of salt out.
Sour dough toast,homemade mustard from here,a little horseradish cream spread,swiss cheese,and a homemade pickle sliced.
Now we are talking GOOD!Mellowed the salt (and remember,yours and mine may be different in how prepared at butchers) And fast and easy,gotta love it.SV on the pastrami I bet is excellent meld of old and new,Hubs I think would be prime,I'm going to do that at some point,I have other brining bacon projects going,and more SV corned beef to do,bought 6,going back for 6 more this is sooooo good.Ya'll are going to be blown away by the texture SV gives this meat.Firm,yet tender as all get out.Not stringy.
