I never used these before.... Bakers choc. semi sweet or German choc. etc. But i have a rec. that says to use the bakes german sweet choc. and i noticed this product comes in a bar instead of indiv. wrapped sq. of 1 oz.. My rec. say to use the german choc. but says 4 (1 oz.) squares. The box says it is 4 oz. wt. Do i use the whole box or just 4 of the squares? THX
