4-5 fresh strawberries, depending on size
Small handful of fresh mint leaves
3 oz simple syrup (even amounts of sugar and water, heated until the sugar melts, and cooled to room temperature)
2 oz rum
1 1/2 tsp fresh lime juice
Place strawberries, mint, and some ice (crushed ice works best) in a tall glass. Muddle the ingredients together with the back of a spoon (or a muddler if you have one.) Add simple syrup, rum, and lime juice. Pour in enough club soda to fill the glass. Give the mixture a stir, and garnish with fresh strawberries and lime slices.
