Notes
Store coconut cream in the refrigerator after opening. It will stay fresh for up to 1 week.Use fresh lime juice instead of bottled for the best taste. One medium lime yields about 1 oz of juice.Make simple syrup by combining equal parts sugar and water in a pot. Heat until sugar dissolves, then cool before using.For a non-alcoholic version, replace rum with coconut water and add a splash of vanilla extract.Keep ingredients cold for the best results. Warm coconut cream can separate in the drink.
