What does Waterless Cooking Mean? This is a method of cooking in which the food is prepared in an environment that is almost entirely waterless. The natural juices present in the food in the form of fats and water are used to cook the food instead of adding grease or extra water.
The addition of solutes lowers the free energy of water and thus lowers the water potential. The water potential of pure water at atmospheric pressure is zero. The flow of water occurs from a region of high water potential to a region of low water potential. For a solution at atmospheric pressure water potential is equal to the solute potential.
