If we are to produce quality frozen foods in the home environment, we most grapple with several physical foes. The first is found in the food itself. The universal ingredient: water. [AB pours a pitcher of water onto the floor, but as the camera cuts to the floor, the water has turned into blue plastic soldier] Now just pretend that all those little blue guys are water molecules, okay? Now when they're in liquid form, they mill around, making and breaking random bonds with each other. But if we remove the heat, that is, if we chill them, they slow down, and eventually they line up like the good little soldiers that they are. We call this process "crystallization". Now if the temperature drops quickly, small crystals result. But if we drop the temperature very, very slowly, we get big, gigantic crystals. What's the effect on food? Let's find out. [at the table] Consider this beef strip steak, which has spent the last eight hours in the freezer. Deep inside, we can see a great deal of the meat's moisture has become bound up in crystals.
