She had her reasons
This story is a bit cute and quirky. Grandma clearly liked her granddaughter enough to give her a lovely and pricey little antique. And yet, Grandma didn’t want to reveal what it was for. What an odd thing to do. We couldn’t have guessed the correct use for this Tiffany’s tool if we tried. Well, this woman finally got her answer after turning to Reddit.
This is a tea or cocktail muddler; it acts as a grinder by crushing herbs between the metal ball and the inside of the cup or glass. Cocktail muddlers now come in all forms, most often plastic, and are often used in bars and restaurants alike. We’ve never seen a Tiffany’s cocktail muddler before. I have a feeling grandma had a few good stories in her.
