I finished this on Sunday, but still have question marks next to two of the clues. I'm sure I'll kick myself when they're explained to me.
11a: File freeing prisoner (not a whopper) (4) Something you remove, say, a lie from to get rasp?
2d: Japanese noodle- cook stuffs one (4) I assume there's either a chef's name or a word for cook that has udon in it.
