Choosing a pineapple is much easier than it sounds. All signs of ripeness are literally "written" on the fruit itself - you just need to pay attention to them and take them into account when buying.
In the store, flip the pineapple over and carefully examine the part on which it stands and where it was once attached to a rosette of leaves. The pineapple on the left (pictured above) is ripe as the root has dried and turned brown, and the area around it is brownish-yellow. On the pineapple on the right, the root is still fresh, and the area around it is greenish-yellow. This means that the pineapple is not yet ripe. You can leave it in a dark place for 2 weeks, and then it will "reach", but if you want ripe fruit right now, then greenish pineapple is not the best choice. The second sign of the ripeness of a pineapple is its overall color. Pay attention to the photo below: the pineapple on the left has a rather brownish-yellow color, compared to the pineapple on the right - it is more greenish, it even looks unripe. Based on two simple signs, you can easily and simply choose a ripe pineapple in the store!
