ok, i understand what a patty pan is. a pan used for baking pies--sweet or savory. this is clear. they come in a variety of sizes; older ones were often quite heavey. fine. but in beatrix potter's children's story "the pie and the patty pan" one of the characters swallows a patty pan that was used to help the top crust of the pie rise. that is, the patty pan was used INSIDE the pie; baked in there. i don't understand what kind of patty pan this was or why it was used in this way. does anyone have insight into why/how a patty pan would have been used in this fashion? thanks and chow, butternut.
