Grease a 7x2” cake pan and set aside. Use 8inch if that's all you have
Sift 3 1/2 cups of the flour, the baking powder, baking soda,and salt into a large bowl. Add the raisins, and caraway and sugar if using and stir to mix.
Combine the buttermilk, egg replacer, and maple syrup in a separate bowl and mix well. (Wini mixed the buttermilk, egg, baking soda but I added the soda to the dry ingredients.)
Pour the liquid ingredients into dry ingredients and stir to mix until you have a soft dough. If it is very sticky, add 2 tablespoons of flour, mix, and decide if you need another 2 tablespoons. (Mine took 2 tablespoons. It will still be soft when it is right.)
Cool the pan on a cooling rack for 15 minutes, and then turn the loaf out onto the rack to cool completely. You should end up with a bread that is smooth and a bit dense.
