The Cocktail bar - Moscow Mule

I'm sitting here, drinking vodka lemonade and thinking what I could possibly do with the 1L of vodka my husband brought back duty free when he came back from Switzerland - and then I thought of the Vodka Mule.

Smirnoff at the moment have an RTD (ready to drink) called Smirnoff Mule at the moment, and I know 3 different recipes for this - I'm gonna give you my favourite first, and then the alternatives, which I'm not so sure on.

• 50 mL vodka (always use Smirnoff - mostly because its what I drink, and its also what tends to be the "house" vodka at pubs I work at)
• Lime
• Dry ginger ale

1. Muddle the lime in an old fashioned glass
2. Add the vodka
3. Add ice to top of glass
4. Top with dry ginger ale

The alternatives I know are using ginger beer, which is much spicier in flavour, and using lime cordial/syrup instead of real lime. If you're gonna use the lime syrup, make sure its the very pale chartreuse coloured syrup, not that dark green-kids-love-it stuff
