- Measure out the fresh pineapple chunks and place them into the blender jar. 
- Squeeze the juice of a fresh lime directly into the blender, then add the lime peel if desired for extra zest. 
- Add the crushed ice on top of the pineapple and lime in the blender. 
- Securely attach the lid and blend on high speed until the mixture is smooth, frosty, and thickened, about 30-40 seconds. You should see a vibrant, icy texture forming. 
- Stop the blender and give the slushie a quick stir with a spoon to ensure even consistency. 
- Pour the pineapple slushie into chilled glasses, watching the icy, colorful beverage settle inside. 
- Optional: garnish with a slice of lime or a small pineapple wedge for a festive touch.
