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 13 cm x 23 cm 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 190ºC . Loaf should be lightly brown on top. Leave in pan until cool and cut with wax paper still in place.
