I swear I'm not making this up. Delta Burke was on a talk show, years ago, and she said she was a great saver of mementos and such. She described shellacking food items to preserve them. Not kidding, I actually heard this come out of someones mouth.
Do you think it would work?
Today I went to a lunch where special cookies were served. I noticed one person taste the cookie, saw a quick grimace followed by a discreet lean to the waste basket. Honestly, the cookie is cute. It's a memento, just not tasty. I want to shellac it, which just might improve the taste! Oh, what is shellac?
