Blue Lemon Martini
To create a signature drink you just have to get creative and add a twist to a recipe you already love. Start with a cocktail recipe you already enjoy, then tweak either the liquor or other ingredients you'd normally use to create something unique. Then, consider giving your drink creation a name that fits the look/feel/theme of your celebration.
3 ounces Tangueray Gin
1/2 ounce Dry Vermouth
1 teaspoon Blue Curacao
1 teaspoon Fresh Lemon Juice
Add all the ingredients to shaker which has been half filled with ice. Shake until chilled, strain and pour into martini glasses.
