steak etcI use the MSS on chicken as well as veggies. Goes great with some butter in cooked spinach or as the "secret" ingredient in twice baked potatoes.
On steaks I use it immediately before putting the steak on the grill and rub it in a bit, nothing too strenuous. I don't put it on right out of the fridge as I let my steaks sit for 30+ mins to get to room temp before grilling. It is definitely salty enough to start leaching if you put it on right away. Different brands have different salt contents but the ones I use are fairly salty.
I also recommend Keg steak spice, similar idea and a different flavor set. For chicken I recommend lawrys seasoned salt over the MSS though. especially on an oven baked, often based chicken. Yum.
