If you’ve read the Harry Potter books, you would have come across a drink called butterbeer. When Hogwarts students visit Hogsmeade, they go to The Three Broomsticks for butterbeer.
But what is butterbeer exactly? The Harry Potter books provide no recipe. The drink is, however, served at Harry Potter theme parks.
According to Wikia:
Butterbeer may be based on Buttered Beer, which was a real drink. The earliest reference to Buttered Beer was from, ‘The Good Huswifes Handmaide for the Kitchin’ published in London in 1588 A.D., made from beer, sugar, eggs, nutmeg, cloves and butter back in Tudor times. Another old recipe for Buttered Beer, published by Robert May in 1664 A.D., from his recipe book, ‘The Accomplisht Cook’ called for licorice root and aniseeds to be added. British celebrity chef Heston Blumenthal recreated it for his Tudor Feast.
On the web, one finds endless fan-created recipes for butterbeer—from clear amber to creamy beige. This is Alex’s butterbeer recipe—ultra creamy, spiked with rum and topped with vanilla ice cream. Super, super delicious!
Make a simply syrup. Boil together the light brown sugar with a cup of water until the sugar is dissolved. Cool. Stir in the vanilla extract and half of the butter extract. Transfer the syrup to a jar with a screw-type cap and chill for a few hours.
In a pitcher, stir together 3/4 cup of the chilled syrup, all of the soda water, rum and the remaining butter extract.
Stir the milk into the whipped cream to thin it a bit.
Divide the whipped cream among three glasses.
Pour the rum-syrup mixture over the cream, leaving enough space for the ice cream topping.
Top each glass with a scoop of vanilla ice cream. Sprinkle in some chocolate shards.
Serve the butterbeer at once.
