Sorry for any confusion, when I make “Thousand Island” at home apparently I actually make Russian dressing. Mayo, Ketchup, Sambal, Chopped Dill Pickle, Chopped Onion, a little horseradish, EVO and red wine vinegar.
I searched out a few recipes for Thousand Island on the web and these are all to sweet for me, I would never put that on a sandwich. For some reason, I always thought the two dressings were the same.
I also occasionally make the Reubens with a good dijon mustard and horseradish instead of dressing, which I have to say I almost like better.
Finally Mr Reuben always has to be slathered outside with a lot of buttah and grilled up in a pan with a sandwich press:
I inherited this from my grandfather who made it himself from a sheet of quarter inch stainless.
