Good base for adding other flavors This serves as a good base to add other ingredients to. I made two quiches. One added turkey bacon, which my little one loved. The other added spinach, sundried tomatoes, Dijon, and Italian seasoning, which I loved. Both turned out great. For the crust, I only used all-purpose flour, since that's what I had on hand; substituted Greek yogurt for sour cream; and added a little more water. Both cooked closer to the 50 minute mark.
