What’s an sq.?
I think it means “squares.”
That’s what I have found as well. But a square stands for an area of 100 square feet. 100 Square feet of chocolate?
I think when you buy chocolate for cooking purposes it is divided into squares. You can break off as many squares as you need for what you are baking.
Bakers unsweetened chocolate used to be packaged in individual 1oz wrapped squares. Now it looks like a fat Hershey’s candy bar and 4 blocks equal 1oz. I found that 2 oz (8 blocks) wasn’t chocolate enough so I’m going to try making it again with 3oz of chocolate (1oz for each cup of sugar).
