Ingredients: mint, lime slices, raspberries, sugar/or simple syrup, rum (a citrus rum works great!), and club soda
In the bottom of a glass muddle the mint, raspberries, sugar, and lime. The more you break up the ingredients the more flavorful your drink will be. Also the amount of each ingredient is up to you depending on which flavors you prefer to be dominant. I like to use a healthy amount of mint and lime.
Add Rum (about an 1oz will do but again you can tweak to taste)
Add Club Soda
