Howdy, drjeff, and welcome to ChefTalk Cafe! Your question is more likely to get the response you're looking for if you post it in the Recipe Exchange forum. I'm a new moderator and don't yet know how to move your post, so please re-post it there. You can also try one of the pastry forums, too.
Good luck! Heirloom recipes are precious, and finding replacements can be very satisfying.
