After watching Heston's Feast I was inspired by my idol Heston Blumenthal in recreating the 1588 Tudor Butterbeer! It looked oddly delicious and I too wanted to conjure up this historical recipe. I found the exact same recipe Mr Blumenthal's used from the website here. For many Harry Potter fans, you'll also know it as the beverage Harry, Ron and Hermione have at The Three Broomsticks.
It was suprisingly delicious. You can really taste the spice, beer and butter! and they all blend in perfectly. Those Tudors really knew what they were doing!!
