Add the baking soda, baking powder, and salt. Mix in.
Add the flour and stir until just mixed. Batter will be lumpy.
I use a stoneware bread pan to bake this. If you don't have one of those. Make sure to butter and flour the bread pan. Or use a handy-dandy loaf liner.
Bake for about and hour. Oven temperatures may vary so keep an eye on it. The bread should be a deep golden brown and a skewer test should come out clean.
