Yes, it looks as if more people know about spanakopita than not, so it's just my ignorance :) Wikipedia describes it as being like borek, and I'd have been fine with that, as I'm familiar with it.

I mind less if it's an actual ingredient I don't know - after all, ramps is ramps - it's the obscure treatments that I find more annoying. I'd be quite interested to meet a new and unfamiliar vegetable :)
