First pick the heaviest pineapple in the bunch, it doesn't matter if it's green. Take it home and if you have a heavy vase turn the pineapple upside down top and all, into the vase and put it on the counter. I couldn't find a vase large enough to fit the green leaves in so I used a milk jug and cut the top off it. In order to allow some air circulation around the pineapple top. I then cut slits in the sides at different heights to retain some of the strength of the milk jug. Turning the pineapple upside down allows it to ripen faster and more evenly.
How To Know When It's Ripe:
When you smell the pineapple and it's yellow in color from bottom to top it is ready to cut. It will have a slight give to the skin but the color and the smell is a better indicator. Cut it up according to the directions and put it into the refrigerator. What a treat, fresh pineapple, I use to cut it way to early and it never really ripened after cutting. This trick works great and is easy to do.
