Yeah, me too! I was thinking "maybe she is from another country" but now it all makes sense.
I googled miniatures and got this. You may want to ask someone who makes things like this for a living. However, Aileens glues make just about any thing you might want. My first thought was some of her puff paint, but just a bit of offwhite glue might work too. You would need to experiment on some of the pies to find if it falls flat as it's drying, but I am sure you will find the right product and method. When you do, can you share it with us? How cute!!
I enclosed a shot of one I took at our local fair. Good luck!!
