Steps

• Place ice cubes in your cocktail glasses.
• Cut the pineapple into small cubes and crush, in a mixing glass, with a muddler (or whatever you have on hand). Add the basil leaves and crush again to extract the flavors and the pineapple juice properly.
• Add ice cubes, followed by fresh squeezed lemon juice. Then add the rum and limoncello.
• Remove the ice water from your cocktail glasses (to avoid diluting the drink). Then pour the cocktail through a fine strainer.
• Garnish with a slice of lemon, pineapple, and a basil leaf. Serve immediately.
