ApplegumPam--you are right. That white foamy mold was made by Elegant Lace Molds..aka Carol Webb at the Cakery. Caljava ( caljavaonline.com ) must have bought her out--but I don't think they are making them any more.. If you go to their website, then in closeout section.., they have a few left, but not this style. They are/were super easy to use, and fast fast fast. I have quite of few of those molds, and use them often.
I uploaded a cake today that used one of their molds.
