My mother was a cookie queen! This cookie is one of the many traditional cookies she would make during the Christmas holiday. They’re know by many names- Thimble, Jam Thumbprint, Swedish Dainties, or Swedish Tea Rings. These are perfect for any tea party, wedding or baby, shower or just to enjoy with a cup of coffee or tea. Be aware you can’t eat just one!
