Instructions
Preheat the oven to 400°F. Line an 8-10 inch cast iron skillet with parchment paper.
In a large bowl, whisk together 3 cups(420g) gluten-free flour blend, 2 tablespoons(25g) granulated sugar, ¾ teaspoon kosher salt, 2 teaspoons baking powder, and 1 teaspoon baking soda.
Add the cold cubed 4 tablespoons(56g) butter and cut into the flour using a pastry cutter or two knives until the pieces are about the size of peas.
Stir in ¾ cup(113g) dried currants or golden raisins until evenly distributed.
In a separate bowl, whisk together 1 ¼ cup(300g) buttermilk and 1(50g) large egg until smooth.
Make a well in the center of the dry ingredients and pour in the buttermilk mixture.
Mix with a spatula until the dough just comes together. If it's too dry, add more buttermilk a tablespoon at a time, up to an additional 1/4 cup.
Form the dough into a disk about 6 inches in diameter. It should look rough and scraggly, not smooth.
Transfer to the prepared skillet. Brush the top with 1 tablespoon(15g) buttermilk.
Use a sharp knife to cut a deep cross into the top of the dough, about halfway through.
Bake at 400°F for 30-40 minutes, until golden brown and a toothpick inserted in the center comes out clean.
Cool for 10 minutes in the skillet, then transfer to a wire rack to cool completely before slicing.
Notes
Buttermilk. Start with 1 ¼ cups. If the dough is too dry to hold together, add more a tablespoon at a time, up to an additional ¼ cup. Do not exceed 1 ½ cups total or the bread will be dense.
Flour. I used Bob's Red Mill 1-to-1 Gluten-Free Baking Flour, which contains xanthan gum. I haven't tested other blends so can't verify they will work.
Weigh your flour. Scooping can vary drastically. A food scale gives the most consistent results. I include gram weights for this reason.
Celiac note. If you have celiac disease or are on a gluten-free diet, double check that all ingredients are gluten-free, as manufacturing practices can change.
