Thumbprint Cookies

This cookie is one of our family favorites. And with all the jam makings in the Carriage House kitchen this year, it seemed fitting that we make a few cookies to showcase all of that work for the holidays.

Grandma Hartsock didn’t use plum jam, but she never got to taste our plum jam. We think she would be proud.

Merry Christmas!
