The most amazing item I've cooked sous vide is shrimp. You can cook them to where they are crunchy and squeak on your teeth.
Awesome..
I was given some 1" steaks which are so easy to over cook.. I sous vide them to 130º then put them in the fridge.
Next day I seared them hot and fast cold.. the outside was browned and the cold protected the inside from getting past the 130º and after the rest they were plenty hot enough to eat..
