You want to select a pineapple that is plump and fresh-looking. In other words, the leaves in the crown should be fresh and green, and the body of the pineapple firm. Keep in mind, a large pineapple does not necessarily mean the fruit will be better tasting or any riper than a smaller pineapple. Also, the color of the shell is not necessarily a sign of maturity or ripeness. A pineapple can be ripe when the shell is practically all green.

Once the pineapple is picked, it will not ripen any further or get any sweeter. So, the sooner they are eaten, the better. If you don't plan to use a fresh pineapple right away, store it in your refrigerator. It will keep longer.
