Thanks for all the replies, and for Pucca sharing the recipe with me.
I did make it for our breakfast dinner tonight and though I didn't have any gluten for puffing purposes, it did a pretty nice job. I also ended up dicing the apples instead of slicing (my 25th reason to get glasses) but I think everything else was pretty much by the book.
Overall I think I'd give it about a 7.5. The recipe calls for sauteeing the apples in a nonstick ovensafe pan, then removing them to a bowl while the sugar/cin/butter/cornstarch topping is placed along the bottom of the pan, and finally topping the sugar mix with the pre-sauteed apples. A teensy bit of a pain but bigger issue is that I always loved the smell and taste of the apples that had been sauteed in the sugar/butter mixture...I thought they caramelized better and somehow absorbed the flavor more than this one.
After the batter is poured over the pan, it's baked at 250 for a half hour, then the oven is to be raised to 500, then reduced to 450 before the puffing occurs. My kids were starving so I actually used one oven for the low heat and turned on the second oven while the first round was baking so I could just transfer to the hot oven and save the 20 minutes preheating time.
The pancake puffed nicely, though unevenly (which may be my oven's fault). I did NOT use the convection for this though I suspect I could have done so, though that early bake at 250 would have to be at 225 and that's mighty low to me.
Anyway, I'll probably try the Gale Gand version this weekend, now that the kids konw there's another recipe they want to compare. I'll try to post on that experience if I get to it.
