Do you call it apple crisp or apple crumble? I've heard it called both. I may have to ask my mother to settle this one. I think whatever you grew up calling it is best. I just can't remember what we called it growing up. I'll post some pictures later.
P.S. Here's another piece of eighties gold. ABC actually have this lyric in "That Was Then But This is Now": "Can't complain, mustn't grumble, help yourself to another piece of apple crumble." I'm not making it up. See for yourself at 1:11-1:20. I guess I mustn't grumble.
