I've had the tiniest nagging confusion about that...
From what I recall, it seemed pretty common to use the recipe on the bag of chocolate chips, yet somehow each family's cookies came out different.
My mom's instantiation of the bag recipe, for example, were pretty consistent across runs, yet not quite like anyone else's (that you're exposed to at friends' houses, school birthdays, bake sales, church potlucks, family reunions, cafes, ad photos, etc.)
