In a ice-filled whisky glass, put 2 parts gin, 1 part milk, 1 part strong, hot coffee. Add a dash of lime cordial, orange cordial and ( if you can find it, lemon-barley cordial )

Next, go to the bathroom, and get some Andrews Liver Salts. Pour into glass.

The drink will start to steam, foam and spit. Garnish with coffee beans, and serve.
