All this talk about Chicago and Chocolate at the Pens made me remember totally delicious childhood (and young adult) memories of going to Marshall Field's for tea and a slice of their frango mint pie. It was pure heaven - a creamy chocolate mousse with just a tad of peppermint in it.
Yes, yes, before anyone points out that Fields still has frango mint pie, (and frango mint candies) it's just not the same. They changed the (secret) formula some years back and lost something in the translation. I'm not sure what they did, but the last slice I had there was but a pale shadow of the original. Sigh. I can dream, though.
