Mix together 1 1/2 cups of flour, 1/2 teaspoon of salt, 1 cup of sugar and 1 teaspoon of baking soda until blended together. In a separate bowl mix 1/4 cup of water, 2 eggs, 1 cup of pumpkin puree, 1.2 teaspoon of nutmeg, 1/2 teaspoon of all spice and 1/2 teaspoon of cinnamon. Add the 2 mixtures together and stir combined. Some choose to add walnuts but this is strictly optional. Pour the batter into a well buttered loaf pan and bake at 350 degrees for about an hour. When you can stick a toothpick in the middle and it come out clean, the bread is done.
