Because I'm failing miserably to create anything edible in mine.
I've seen no less than three other women produce the most magnificent starbucks-muffin-sized yorkshire puds in theirs, but today I managed to make the flattest puds ever - practically pancakes. Yesterdays attempt was uncooked in the middle!!
If you do it, tell me how. I bought the damn thing on the promise that massive, tasty yorkshire puds would be mine!!
