The first pie I mastered was Door County Cherry Pie. This was the pie we had at every holiday while I was growing up and is still my favorite. When I moved to Maryland, those tart little Door County cherries were no longer available to me, and I had to relearn cherry pie with the larger, sweeter bing cherries that are so readily available out here. While I struggled with the unfamiliarity of these cherries and tried to get some of that tart cherry flavor I grew up with into my pies, I eventually began looking to other fruits. And, in my trusty Betty Crocker cookbook, I found what would become the signature pie of my early days as a wife - Apple Sour Cream pie. I made this pie so many times it became My Pie. And, even though I haven't made it in years, I still think of it that way.
