To make a perfect martini start by icing up a metal shaker. Then start adding the ingredients beginning with 2 ounces of premium tequila, 1 ounce of Cointreau liqueur, 1/4 ounce of Roses Lime Juice, and 1/2 teaspoon of granulated sugar. Put the lid on the shaker and shake the drink up. Moisten the rim of the martini glass with a lime, and then dip the glass in salt to coat the rim of the glass with salt. Pour the mix into the glass, and then put a slice of lime on the rim of the glass, and you have a nice tasty refreshing drink.
