Craig and Kirk , we used to make our salt crusts out of rock salt with liberal pepper rubbed on before making the crust. When the salt was applied , a spray bottle of water helped the salt crust set up. Yes, no overly salty taste when done. It was super to use a bone in prime rib. A bit later the bones could be used for bbq ribs. Oh, so good. This was all a slow cook procedure at under 300 degrees for hours. All worth the wait. Now, with no kids around, a big prime rib is too much, but I sure do enjoy thinking of it.
