Turn the oven on to 425°F and make sure the rack is set in the middle for even cooking.
02 -
In a large bowl, stir the flour, baking soda, sugar, and salt together until blended.
03 -
Rub the butter into the dry mix with your fingertips until it looks like crumbly bits.
04 -
Toss the raisins or currants into the mixture, making sure they're spread out evenly.
05 -
Make a big open space in the middle of the dry ingredients for adding liquids.
06 -
Pour the buttermilk and whisked egg into the space and mix gently with a wooden spoon until it starts getting tough to stir.
07 -
With floured hands, bring the dough together into a rough round shape without kneading too much.
08 -
Sprinkle in more flour gradually if the dough is too sticky to handle, but don't overdo it.
09 -
Move the dough onto a floured countertop and form it into a nice round loaf without overhandling.
10 -
Put the dough on a baking sheet or into a greased cast iron skillet.
11 -
Cut a deep X across the top using a serrated knife. This helps it bake through evenly.
12 -
Bake it in the oven for 35 to 45 minutes until it's golden and sounds hollow when tapped.
13 -
If the top looks like it's browning too much, cover it with foil partway through baking.
14 -
Push a skewer into the middle of the loaf. If it comes out spotless, it's done.
15 -
Let it sit in the pan for about 5 to 10 minutes, then transfer to a rack to cool down entirely before slicing.
