If the avocado yields to firm gentle pressure you know it's ripe and ready-to-eat. Ripe, ready to eat avocados may have a darker color but color can vary so it is best to go by feel as well as color. It will feel lightly soft but it will not feel “mushy” to the touch.
Is a soft avocado bad?
Avocados are rotten if they're mushy when squeezed, brown or moldy inside, and have developed rancidity or a sour smell. You may be able to salvage part of the fruit if it's just starting to brown inside and the rest of the fruit looks, smells, and tastes fine.
Can you eat avocados that are not soft?
Can you eat an avocado that is not ripe? Yes, you can eat an unripe avocado, but we don't recommend it. The avocado won't have its wonderfully creamy texture and it won't taste as delicious as normal.
