Butterbeer Recipe!

I'm a HUGE Harry Potter fan. I grew up with the characters. If you're like me, you always wanted to go to Hogsmeade and Diagon Alley. Heck I still do. One of the things I've always wanted to try is Butterbeer. I've looked all over the recipe trying to find a recipe that I feel tastes like what the books described. I've found many recipes although none quite lived up to what I had imagined. So I tweaked one of the recipes I found.

Ingredients:

• 2 1/2 tsp water 
• 1 cup light brown sugar
• 1/2 tsp salt
• 1/4 tsp apple cider vinegar 
• 1/2 tsp rum extract
• 1/2 tsp vanilla
• 1 cup heavy cream, divided
• 6 tsp butter
• 4 12 oz bottles of cream soda (very cold)

Directions:

• In a small pan over medium heat, combine brown sugar and water. Bring to a boil. Boil until mixture reaches 240 degrees F on a candy thermometer. 
• Add in butter, salt, apple cider vinegar and 1/4 cup of the cream. Remove from heat and allow to cool to room temperature. 
• Once the mixture has cooled, add in rum and vanilla extracts. Mix well. 
• In a bowl, pour the remainder of the cream and 2 1/2 tbs of the brown sugar mixture. Using a hand mixer, beat until thickened. It should be frothy looking. 
• Divide the brown sugar mixture between 4 tall glasses. Pour is 1/3 cup of cream soda and mix well. Pour cream soda into the glass until almost full. Add the froth to the top. 
• Now watch your favorite Harry Potter movie and enjoy your delicious Butterbeer.
