Start by ordering a Grande Green Tea Frappuccino.
Then, ask for one pump of white mocha and one pump of peppermint syrup.
And finally, ask for some crushed strawberry inclusions on top of the whipped cream.
And viola! You now have your very own Winifred Sanderson Frappuccino, perfect for our spooky season coming up and for our Hocus Pocus marathons that we know will happen.
