A Half-Dozen Buttermilk Biscuits

These were simple, had a nice rise in the oven and tasted pretty good. I felt there may have been a tiny bit too much baking soda - I got a little taste of it with a couple bites. I did notice that unlike my usual buttermilk biscuit recipes, this called for more baking soda than it did powder. Not sure if this could be a misprint?? Maybe the called for amounts should be swapped to 1/2 teaspoon baking soda and 1 1/4 teaspoon baking powder??
