Wow ya'll have been on a roll! I didn't have access to my internet for a few days and saw all of the new posts... the "Toad in the hole" cracked me up - ew!
If anything, I'm tickled pink that a few of you who hadn't heard of it before tried it with successful results!
And on the 'why save the hole' question, all of the responders were great with their reasons. My DH saves his hole for the yolk (yuck - I'm not a yolk fan unless it's been scrambled or cooked well done) and I save my hole for for the extra bread.
