I was searching for this recipe for years! They are great! The sour cream and yeast make a cookie with a very unusual texture and taste, crisp, flaky and chewy all at once. My DH and I both love them.
These are wonderful! My family has been baking them since the 1960's. They aren't too sweet and are very light. It is an unusual recipe but people usually love them and they are worth the effort. I was shocked to find them online!
