Thanks to Dinah Bucholz for this and her other delicious recipes found in The Unofficial Harry Potter Cookbook and The Unofficial Harry Potter Sweet Shoppe. Hagrid’s glue-your-teeth-together fudge turns out to be quite useful after Hagrid has been taken to Azkaban, Harry feeds some to Fang to keep him quiet. Fang can not bark because his fangs are stuck together. Fudge is not foolproof, so it is no surprise Hagrid’s did not come out quite right.
Making fudge was the “in” thing to do at women’s colleges in the 1880s. Can you imagine if that were the case today? Times have certainly changed. We do not know who invented fudge, though some speculate that a batch of caramel came out wrong – it was “fudged” – but it seems it was invented in the United States.
