The answer to how to ripen a pineapple starts with choosing a good one at the store.
The fact is that pineapples stop ripening the moment they are removed from the plant.
However, green pineapples can be masked with the use of ethylene gas.
Quick Hint: If pineapple is ripe in the store, it will smell sweet
This gas is not as dangerous or as scary as it sounds.
They come naturally from other fruits like pears, nectarines, and apples.
When the pineapple is placed in a paper bag with any of these fruits, it will change color from green to yellow.
Although on the outside these green pineapples may appear to be ripe, inside, the texture and taste often remain the same.
This is why it is better to pick the perfect pineapple rather than simply trying to ripen it once it has already been purchased.
This became important to us for our pineapple salsa.
To avoid having to ripen the pineapple, you should know how to find a good one, to begin with.
When buying from the grocery store, look for pineapples with a fresh and plump look.
Go for the ones with green and fresh leaves on their crowns.
(We provide a step-by-step guide below.)
Contrary to popular belief, you should go for those with firm bodies and not for those that are soft.
Another thing to keep in mind is that larger fruits do not translate to better taste.
More importantly, remember that shell color does not entirely signify ripeness.
In fact, there are yields known as “green-shell ripe”.
Just because fresh pineapple is green does not mean that it’s unripe.
Another good indicator of ripeness is the scent of the fruit.
Look for those that emit the sweet scent of pineapple.
More than its color and other physical characteristics, this is a good indicator that the ripe fruit is ready for harvest or for consumption.
Look (Visual Inspection) – One of the fastest ways of determining a good pineapple is by the way it looks.
Color – Look for those that are wide with a deep color instead of pale-looking ones.
Inspect the top – The crown should be green, firm, and fresh.
Squeeze it – See to it that the fruit is firm and not squishy or soft. Contrary to popular belief, softness does not equate to ripeness.
Flip it – One important tip is to check the fruit’s base and see if it has some red or orange color in it.
If there is none, the fruit was picked too early and it is most likely unripe.
Smell it – Finally, the best indicator is the scent.
Smell the base of the pineapple and check for its tropical aroma.
If there is no scent, the fruit is not ready yet.
On the other hand, a fermented or sickly sweet scent indicates it is overripe.
You don’t want this either.
A good pineapple smells sweet.

Method 2 – The Upside-Down Method
The first method involves standing the fruit upside down on their leaves.
This method allows the pineapple’s natural sugars to flow all the way down to the core resulting in faster ripening.
At the same time, this method also stops fermentation from happening on its base.
One of the frustrating issues that can come up with pineapple is the bottom getting mushy and overripe and the top not being ripe yet.
There is a simple process to help prevent this from happening.

Once the pineapple appears ripe, place it in the refrigerator on its side.
Don’t leave it upside on the counter after it is ripe because this process will shorten the life of the pineapple if it isn’t properly stored afterward.
