Butterbeer III

• 1 cup brown sugar
• 2 tablespoons water
• 6 tablespoons butter
• 1/2 teaspoon salt
• 1/2 teaspoon cider vinegar
• 1/4 cup heavy cream, divided
• 1/2 teaspoon rum extract
• 1/2 cup heavy cream
• 4 (12 fluid ounce) cans or bottles cream soda

1. Stir the brown sugar and water together in a small saucepan over medium heat; bring to a gentle boil, and cook until the mixture reads 240 degrees F (115 degrees C) on a candy thermometer.
2. When a small amount of the syrup is dropped into a glass of cold water, it should form a soft ball.
3. Add the butter, salt, cider vinegar, and 1/4 cup heavy cream, and stir.
4. Remove from heat and set aside to cool completely; mix the rum extract into the cooled mixture.
5. Combine 2 tablespoons of the brown sugar-cream syrup with remaining 1/2 cup heavy cream in a non-plastic bowl; beat with an electric mixer until whipped and cream holds soft peaks, 2 to 3 minutes.
6. Pour about 1/4 cup of the remaining brown sugar-cream mixture into a tall glass; stir about 1/4 of a bottle of cream soda into the cream mixture.
7. Top with the remainder of the cream soda in the bottle.
8. Top with about 1/4 of the whipped cream.
9. Repeat with 3 more glasses to serve.
