Join Molly Baz in her home Test Kitchen as she makes sour cream and onion biscuits. If you've ever had trouble making biscuits in the past, consider this recipe your saving grace. While many other methods count on pockets of butter and an angel’s touch for pull-apart flakiness, we weren't willing to leave it to chance. Our simple folding technique manually multiplies the number of layers for guaranteed, no-risk success. And the sour cream isn’t just a gimmick.
