Before I forget, the egg didn't go into that filling mix. Well, I guess the yolk did, since I didn't find an egg yolk sitting around when we were done. But it could have been disposed of without my knowing. Still, I think the yolk went in there.
The important bit is this egg white business, which I *THINK* had just the teeniest bit of water added to it. This here becomes your egg wash, which you use to make sure everything is all sealed good and everything.
Ok, that's out of the way. *WHEW*. Hope you didn't add the whole egg to your filling, or you'll be feeling pretty silly right about now!
And yes, this dish does, in fact, contain egg white. Can I help it if egg white is clear (and not white, not that that would help anyway)? No, I don't think so! It's there!
