Two cups cake flour
Two teaspoons baking powder
One half teaspoon baking soda
One half teaspoon salt
One half cup cold butter
Three quarters of a cup buttermilk
Milk, for brushing the biscuits
Preheat the oven to four hundred and twenty five degrees
Into a bowl, sift together the flour, baking powder, baking soda, and salt. Blend in the cold butter until the mixture resembles meal.
Add the buttermilk, stir the mixture until it just forms a dough, and gather into a ball. On a lightly floured surface knead the dough gently six times and pat it out into a rectangle, roughly one half inch thick.
Using a knife, divide the dough into twelve even sized squares. Separate the squares and invert the squares onto a lightly greased baking sheet.
Brush the tops of the squares with the milk, bake the biscuits in the middles of the oven for twelve to fifteen minutes, or until they are pale golden, and transfer them onto a rack. Serve the biscuits at room temperature with poha butter.
