Wow! that looks delicious! I have not heard of disposable paper baking moulds before. any refs?
I used to live in CA and we had two persimmons trees while growing up. they work great in things like this. my mother made persimmons 'pudding' every fall.
I got these from Amazon. But I have also bought them from King Arthur Flour. And there is another suppliers but I can't remember the name of the vendor at the moment.
