Gather the
outsides of the biscuit dough all the way around the biscuit and bring those edges up to the middle and press them into the middle to seal.
I also used buttermilk throughout, skipping on the whole milk and, since I had no chives on hand (and didn't have the courage to fight the mob at Whole Foods), I left them
out of the biscuit dough and added a bit more cracked pepper instead.
