Twas I, my dear. We could bring our versions of lembas with us to Entmoot, no sense in using ksen's oven! I'll just have to look long and hard for some mallorn leaves in which to transport them!
Sounds like fun to me, though I'll have to do a bunch of experimenting between now and then to try to come up with something that at least somewhat resembles how I imagine it.
How come there wasn't any lembas in the movie?
