This is a perfect cocktail to serve to people who are not keen on the taste of alcohol. Adjust the sugar syrup based on the sweetness of your pineapple. Light and fruity. Would be perfect on an afternoon, brunch, or before dinner. Very pleasant.
I do not recommend a rich syrup if you are using a pineapple from a southern country, since they are usually really sweet already. Used 1x1 syrup and slightly more (some 0,05 of an ounce) of rum. Delicious cocktail.
