It's that last measurement that got me... I remembered from making my peppermint bark that the recipe called for 12 oz of white chocolate, and then I remembered measuring out 170 grams (which incidentally was half of the white chocolate in the recipe as I melted the top & bottom layers separately). So long story short - I used exactly half of the chocolate in this fudge recipe and, not surprisingly, it didn't really set. What is surprising is that it almost set, and it tastes amazing!
So instead of bars of chocolate fudge, we're now going to have fresh strawberries with chocolate fudge spread! You can't be perfect all the time, right?
