Opening the pack for further inspection (this was official business here, people), this is what I found.
Q: How many shortbread(s?) make up 100 calories?
Overall, I enjoyed all 100 calories of shortbread. It was a satisfying and tasty snack, and I was happy to see that a fair amount of shortbread were in each pack. Sometimes when passing by these packages I secretly wonder if there is only about 1 cookie per package, however, these fears (probably not a fear, more of a concern perhaps) were unfounded.
I wonder how big a 100 calorie pack of cheesecake would be? Probably better not to find out.
