Semi-Sweet Chocolate bits I have a recipe from maybe the 1950's that calls for 1 pkg semi-sweet chocolate  -  I seem to remember a smaller bag than what I find in the stores.  Might this be 
6 ounces it is calling for?   The recipe is for a Chocolate Satin Pie.
A "package" of bittersweet or sent-sweet baking chocolate was historically 8 ounces, as eight 1-ounce squares (or 16 half-ounce half-squares).
