Gorgeous and delicious. The combination of cheese, basil, and tomato is classic, and for good reason. The mayo gives it a lovely tang and creaminess. And the sour cream pastry is some of the most flavorful, melt-in-your-mouth crust I've ever tasted. I did give up on rolling it out and patted it in the pie plate after several failed attempts to move it. And the 5 minute standing time after baking is crucial. It was still a bit crumbly at that point, but after resting for 10-15 minutes, I was able to slice and plate the pie. This is an excellent addition to a lovely spring brunch.
