Sally's Buttermilk Cookies

My mom by love has been making these cookies for our family for some time now. She got the recipe from her friend Sally who got the recipe from her grandmother.
They are soft and tender and freeze wonderfully. I usually take out one cookie from the freezer. . .putting it aside to thaw. ..but have yet to taste it completely thawed . .. .since I just can't wait.
