Cyn, I have toffee from our local shop. Here is the data for that:
I have it packed in a 8-oz glass canning jar.
The toffee is 1/2 thick pieces; most are 1.5" (rough) squares
All together the 4 large, 4 smaller pieces weight 4 oz.
If I lay them out, they make a rough square of 5" x 3".
I chipped a crown on toffee once and that bugger cost me a $500 copay. So I don't eat it anymore...this was for gifts.
