And it worked. Because these things rise so much, it's recommended that you fill alternate cups in a muffin tin to keep them from blooming into one gigantic popover. Even with the muffin tin gaps my popovers got dangerously close to one another. While it seems like a lot of people had problems with their popovers sticking to the muffin tins even after greasing, mine slid right out of the nonstick tins. Many were rather dark on the bottom (fortunately Mr Leaven likes 'em burnt) and almost all were entirely empty at their centers (fortunately Mr Leaven likes 'em soulless). I think they were supposed to have a doughy interior - not sure what I did wrong but I won't bake them quite as long next time.
We ate some plain and some with butter and honey, and they were all lovely. With a recipe so very simple, I will definitely be making these again. The very simple recipe can be found in the Baking with Julia cookbook or at the blogs of the hosts for this Tuesdays with Dorie challenge (which should have been posted on August 20, if I were a good blogger): Paula and Amy.
