Put a kettle on with about 4 cups of water in it. While this is heating, take your pineapple and give it a wash in the sink with soap and warm water. Just lather it up and give it a good rinse. It's a little strange, but trust me. Then put it on your cutting board.
Then move your cutting board because you realize you don't have enough counter space right here. =) Cut off the top and bottom and discard. (Unless you want to wait 2-4 years for the grow your own pineapple experiment, then save the top.) Stand the pineapple up and carve away the skin until it looks like this:
Look at that juicy goodness. Keep all those bits that you carved away and put them into a pitcher. Then continue to cut up your pineapple, also removing the tough core from the center.
Now here's the hard part. Let it sit for 24 hours at room temperature. =) Then strain and put in the fridge for a cool, refreshing drink. It's really that easy.
