This Irish Soda Bread is some of the most basic bread you can make. There are no fancy-schmancy ingredients in it. Flour(s), sugar, salt, baking soda, and buttermilk are all you need. What's even better is that by using a kitchen scale, you can substitute in whatever flour mixture you like. (I used 150g potato starch, 100g brown rice flour, 100g white rice flour, 100g sorghum flour.) I also love that it doesn't require yeast since yeast tends to trigger migraines for me.
