Profiteroles?

[Carol]

Emma Watson recently commented that she's been filling up on
profiteroles during the filming of Slughorn's Christmas party for HBP:

What on earth are profiteroles?

Carol, happy that the Christmas party will be in the film and hoping
that the Snape/Draco confrontation will be there, too, as close as
possible to the book version
