Sunday Brunch: Lemon Scented Popovers
I used this recipe from Epicurious and added 1 tbsp of lemon zest and 1 tsp vanilla. I think the lemon flavor would have been more pronounced with a tablespoon of lemon juice, or a bit of lemon oil, added as well. I will definately do this in the future.
Be sure to butter the muffin pan really well, because popovers stick like crazy. Also, if you poke a knife or skewer into the top of each popover halfway through baking, some of the steam will be released and you'll end up with a crisper shell and a popover that won't deflate.
