Combine rice flour, salt and baking powder. In a separate bowl, combine remaining ingredients and let set until bubbly. Sprinkle water on the bottom of a 5" x 9" loaf pan and place a piece of wax paper so that it sticks to the bottom, then oil and flour the sides. Combine both mixtures and pour into pan. Bake for one hour at 375 F. Loaf should be lightly brown on top. Leave in pan until cool and cut with wax paper still in place.
