In the past I have smoked my corned beef. Meathead and many others include a desalination step - soaking the store bought brisket for 4-8 hours- before cooking. Is this something I should do when cooking it sous vide? I notice that many use the ChefSteps recipe with s store bought brisket and rave about the results but few mention soaking the brisket. Isn't it too salty without this step?
