Begin by peeling and chopping a fresh pineapple into sizable chunks, ensuring to remove the core.

In a smoothie maker or food processor, combine the chopped pineapple with the juice of one lemon and 1 cup of water. Blend on high for about 30 seconds, or until the mixture is smooth and frothy.

To achieve a smoother consistency for your Pineapple Mocktail, pour the blended mixture through a sieve or fine mesh strainer into a large bowl or pitcher.

For a touch of elegance, prepare your glasses by dipping the rims in water and then into granulated sugar, creating a frosted effect.

Fill each prepared glass with ice to your liking, allowing the chill to enhance the drink's refreshing quality.

If desired, grill fresh pineapple slices for garnish, or simply cut fresh slices. Tuck a few mint leaves on top of each drink and serve immediately.
