Make a Margarita!
If you are new to making your own cocktails, start here. A Margarita is a classic, and a hit every time. You will need Tequila, Cointreau (or Triple Sec), the juice of several freshly squeezed limes, crushed ice and coarsely ground sea salt.
Moisten the rims of your cocktail glasses with lime juice and dip them into the salt to coat the rims.
The proportions of Tequila to Cointreau to lime juice are 3:2:1. Shake these ingredients in a cocktail shaker with crushed ice and strain into your glasses. Cheeers!
