Pour the canned pineapple chunks along with their juice into the blender, letting the bright aroma fill the air.
Add the coconut milk to the blender, creating a creamy base that will meld with the pineapple’s sweetness.
Fill the blender with 1 to 1.5 cups of ice, depending on how thick and icy you want your slushie to be. More ice makes it more chilled and scoopable.
Pulse the blender a few times to start breaking down the ice, listening for the crunch and feeling the mixture becoming chunky and cold.
Blend on high for about 30-45 seconds until the mixture is smooth, frosty, and has a scoopable, slushy consistency.
Stop and taste the slushie; if it’s too tart, stir in a teaspoon of honey or agave syrup for extra sweetness.
Squeeze a splash of lime juice into the blender for a bright, tangy kick, then briefly blend to combine all flavors.
Pour the chilled, icy mixture into a glass or Mason jar, and garnish with a small pineapple wedge or cherry if desired.
Serve immediately with a straw or spoon for the perfect cool-down on a hot day, enjoying the bright, tropical flavors.
