1 3/4 cup buttermilk (plus more for brushing the top)
6 tablespoons melted butter (cooled)
Instructions
Preheat the oven to 375 F.
Grease a large, seasoned cast iron skillet or grease and flour a large baking sheet.
In a large bowl, combine the flour, baking soda, cream of tartar, salt, and sugar. Add the currants and stir to blend.
In another bowl, combine the egg and buttermilk; whisk to blend and then add the melted butter.
Add the egg and buttermilk mixture to the dry mixture and stir until blended. Dump the dough out onto a floured surface and knead for a minute or two, or until it is firm and cohesive. Add extra flour to the dough if it is too sticky.
Shape the dough into two round loaves or, if baking in a skillet, into one larger round loaf. Brush a bit of buttermilk the dough and sprinkle lightly with flour.
With a sharp knife or razor blade, cut an “X” into the top of the loaf or loaves.
Arrange on the baking sheet or in the skillet and then bake the bread in a preheated 375 F oven for 55 to 65 minutes, or until the bread is golden brown.
