STUFFING

Yup, it is. The object of brining is to get moisture into the bird not water log it, or bloat it. Osmosis baby... When you wash the bird, inside and out, the salt washes off.

What does brining do?
Brining is the soaking of meat in a solution of water and salt. Additional flavorings like sugar and spices can also me added, but salt is what makes a brine a brine (just like acid makes a marinade a marinade). This soaking causes the meat to gain some saltiness and flavoring while plumping it up with water so that after cooking it still contains a lot of juices.

The explanation for why brining works that I hear most often is that by surrounding the meat with salt water, salt and water are forced into the tissue through osmosis. Unfortunately, I've never been happy with that explanation. Osmosis is when a solvent (usually water or other liquid that can hold another substance, called the solute, in solution - like salt) moves from a low solute concentration (like the tissue of the meat) to a high solute concentration (like the salt water) through a semipermeable membrane (a surface that allows small particles to pass but not larger ones - like the cell membranes of our chicken or pork) to form an equilibrium. Hmmm... wait a minute. If that's true then water will be drawn from the low salt concentration meat to the high salt concentration salt water. At the same time, if the salt can enter the meat (which it can), then salt will be moving from salt water to meat. Won't that result in a salty, dry piece of poultry or pork?

Obviously, there's more going on than simple osmosis. It is true that salt enters the meat (it tastes more salty after brining). But why is it also more juicy? Well, when water flows out of the meat, salt flows in and begins to break down some of the proteins in the cells. In the broken down state, the molecules become more concentrated and the solute levels rise within the meat. This causes additional water to flow into the meat.

But doesn't that mean we've got the same amount of water as before brining? Nope. The cell membranes are semipermeable. They allow salt and water to flow in both directions freely, but larger molecules (like the denatured proteins and other solutes in the meat released by the salt) cannot flow out from within the cells. When the solutes of a solution on one side of a semipermeable membrane cannot pass to the other side, osmosis causes more and more solvent to move through the semipermeable membrane. This continues until the extra pressure from holding more solvent equals the rate at which solvent is "drawn" through the semipermeable membrane. (This rate is called osmotic pressure. How Stuff Works has a short article describing osmotic pressure with a diagram that may be helpful to visualize the water flow.)

What has happened is that through brining, we've caused a state change in the cells so that they will draw and hold more water than before. As we cook the meat, the heated proteins will begin to draw in tighter and squeeze out water, but, hopefully, enough water will remain to produce a juicy, tender piece of meat.
