Sugar Crinkles

I have had this recipe for years.  They are delicious and so quick and easy!  If you're in the mood for sugar cookies, but don't have the time for the traditional recipe, these are a great substitute.

1 c shortening (I do half butter, it's really a must)
1/2 c sugar
1/2 c brown sugar
1 egg
1 t vanilla
Cream this together. 
Add to creamed mixture:
2 c flour
1/2 t soda
1 t cream of tartar
1 t salt
Mix well.
Roll 1 tablespoon dough into a ball.  Roll in sugar.  Place on an ungreased cookie sheet.  Do not flatten.  Bake 10 minutes (or a little less) at 350.  Makes about 30 cookies.  (in an effort to make these festive, I used colored sugar.  I only had large granulated.  They weren't quite as yummy with the big chunks.  Use fine colored sugar, if they make it. Or just don't bother!!)
