Stanolitan

The Stanolitan (Stanley Cosmopolitan), a drink I created at said party:

Combine 30ml (1oz) of gin with 60ml of Cranberry Juice.
Squeeze some fresh lime in. Stir in half teaspoon of sugar.
Top with ginger ale.

These are not the exact proportions. I made a jug full of this then adjusted the proportions to taste. That is just a very rough outline. I suggest making a batch yourself and finding out.
