Another reason for using standardised units of measure. SI units have made it 
into Australia for everything except the blood pressure and linear units of 
measure now, with centimetres still in use for height. (oddly, my spouse, 
trained in the building industry, doesn't comprehend a centimetre, only mm 
and metre.)

Peanut Blossoms

4 cups sugar           16 tbsp. milk
4 cups brown sugar     4 tsp. vanilla
4 cups shortening      14 cups flour
8 eggs                 4 tsp. soda
4 cups peanut butter   4 tsp. salt

Shape dough into balls.  Roll in sugar and bake on ungreased cookie
sheet at 375 F. for 10-12 minutes.  Immediately top each cookie with a
Hershey's kiss or star pressing down firmly to crack cookie.  Makes a
heck of a lot.
