How to use a bottom concave ebelskiver (Æbleskiver) pan on a glass cook-top stove? I've recently come in to a lovely cast iron ebelskiver pan (pictured below) and would like to try to make some  ebelskivers. 



The problem is I don't have a gas range and I'm rather sure that my glass-top stove won't be able to adequately or evenly heat the pan due to its concave underbelly. The bottom of the wells aren't even level with the skirting rim of the pan.
Is there anything I can do short of replacing my range top or starting a fire in my backyard to use this pan to make some stuffed pancakes?
You could consider heating it up, while empty, in an oven (I would go for, say, 200C/390F). Keep it there for at least 30 minutes: the transfer of heat from the air to the cast iron is not very efficient! Then take it out quickly, pour the batter in, and return it to the oven until done (and then make the next batch, if you're making multiple).

An issue with this could be that the Æbleskiver might cook too quickly from the top. You might need to experiment with the target temperature you leave the oven at.
