Don't you need to brush the filo with butter?

Thanks for your help. I don't have a vast experience with filo, but all recipes I tried you have to brush the sheets with butter or spray them with oil. I'm sure you're right.

It appears from the recipe that you need only brush the top of the phyllo rolls with butter. Seeing that it was reviewed and that the tester had good results, I would feel comfortable following the recipe as written.
