First up, a long overdue post on my experiment with jam filled popovers.
I started with the basic popover recipe out of the joy of cooking. But I decided I wanted to see what would happen if I put jam in them before they went in the oven (because it's so hard to put jam on them after they come out of the oven and you just want them all to be in your mouth). So each popover got a little dollop of jam right before the whole thing slid into the oven.
The end result!
The results were delicious, but stuck to the pan. Apparently the jam both sinks and also rises as its liquids boil away in the oven. The part of the popovers that stuck to the well greased pans were the jelly lined bottoms. Another interesting result was that almost all of them had holes clear through the entire popover (as modeled by Matthew). Delicious as they were, I think next time I will stick to normal popovers and adorn them to my hearts content (and burning fingers displeasure) after they come out of the oven.
