In a blender, blend the pineapple and 1 cup water together until your desired consistency is reached. I don't mind a little chunkiness, but you can blend it super smooth and strain it if you'd like.
Add lime juice to taste, depending on how sweet/tart your pineapple is.
Serve over ice.
Recipe Notes
These pictures feature glasses with sugar rims, but salt could be fun if you want margarita vibes! And at that point, you can add tequila if you want and make it into a matador.
