When comparing a group of avocados, check the outside color of the skin of the avocados for any that are darker in color than the others. These may be riper than avocados with lighter skin.
Once you've picked an avocado, you can test it to find out its ripeness.
Place the avocado in the palm of your hand.
Gently squeeze but don't apply fingertips as this can cause bruising.
If the avocado yields to firm gentle pressure, it is ripe and ready to eat.
