1 dash of grenadine syrup
5-6 oz of soda water
1 of lime
1 oz of bacardi big apple rum (or pineapple rum)
Fill glass with ice, pour in apple bacardi and fill the rest of the way with soda water leaving a little room at the top. Pour a small amount of grenadine on top, just enough to give it a slight color. Squeeze a lime wedge on top and stir.
