My wife and daughter went to the new Universal Studios Harry Potter theme park recently, and raved about the butterbeer. I've looked around the internet for recipes, and mostly, they seem to be versions of butterscotch cream soda. They're all mixtures of other ingredients, such as butter, brown sugar, cream soda, sometimes actual cream, spices, etc. Some are adult versions using butterscotch schnapps, most are sweet kids drinks.
From the descriptions in the books, butterbeer can be intoxicating, so I imagine it really should be brewed, not mixed. However, they do give it to children, so the alcohol content must not be too high, or else there's also a kids version in the wizarding world.
So, now that I've established myself as a complete geek, does anybody have any ideas for actually brewing butterbeer? I would think something along the lines of a cream soda or root beer, with some sort of butterscotch flavor would be the thing. Or am I the only one who has seriously considered this?
