Put water on to boil. In a large cowl combine the cornmeal and salt. When the water boils, measure it in a metal or tempered-glass measuring cup and measure 2 full cups water. Pour the boiling water over the cornmeal and stir. The cornmeal will swell up, absorbing the water and making a very thick mash. Heat a very well oiled large skillet over medium high heat, re-oiling the pan after each batch. Scoop out about 1/4 cup of hot mash and shape into a patty. Fry the cakes in hot oily skillet until brown & crispy on both sides.
