, I have that exact Snickerdoodle recipe! Mine is actually in my Mom's 1963, First Edition "Betty Crocker's Cooky Book".
Besides the cooky book, I also have a Betty Crocker Snickerdoodle mix on hand. They both use cream of tartar and soda. Hmm, wondered why I had that container of cream of tartar in the pantry.
, you said cream of tartar should be good for a long time. As in decades?
I might consider a new one if I get around to baking snickerdoodles.
, my cooky book lists "1 cup shortening (part butter or margarine)", so back in 1963 they were using a combination. T&T!
