In a bowl, add the bread flour, barley flour, light brown sugar, baking powder, baking soda and salt.
Using a whisk, mix well, making sure all the dry ingredients and well combined.
Wet Ingredients:
Drain any remaining stout from the Irish Stout Soaked Currants or Raisins, into a 2 cup liquid measuring cup. Add enough buttermilk to equal 2 cups in the measuring cup. Add this to the dry ingredients, along with the currants/raisins.
Mix until the ingredients form a large dough ball.
Divide the dough into two equal sized balls. Roll each into a sphere, then place them onto a sheet tray, lined with either a Silpat Silicon liner or parchment paper. Using a knife, make an X into the center of each dough ball.
Glaze Ingredients:
In the liquid measuring cup, add the buttermilk, brown sugar and salt. Using a pastry brush, blend the ingredients together. Lightly brush the outsides of each dough ball, making sure to coat evenly. This will give the finished loaf a beautiful golden crust, plus a sheen.
Place into a preheated oven and bake until the Irish Soda Bread registers 200°F | 93°C, about 45 – 55 minutes.
