Now, if you give it time, and I’m talking 45 minutes for a thick steak, up to a day for a big roast, that pulled moisture dissolves the
salt, creating a concentrated brine. And then, through diffusion and osmosis, that brine gets re-absorbed back into the meat, carrying the
salt seasonings deep into the muscle fibers. It seasons from the inside out. The result? Meat that’s seasoned throughout, not just on the crust, and that actually retains
more of its natural moisture during cooking because the
salt has helped the proteins retain
water. I do this with my
pork shoulder every single time. The night before, I give it a heavy, even coat of
salt (and my rub, but the
salt’s the key). By morning, the surface is tacky, almost dry to the touch: that’s the brine fully absorbed. That shoulder cooks up juicier than one I salted right before it went on the smoker. Every time. It’s not magic, it’s cell biology.
