Gently flick the small stem or cap at the top of the avocado. If it doesn’t come off easily, the avocado is likely not ripe yet.
If the stem comes off easily, it’s a good sign that the avocado may be ripe.
Check Under the Stem:
Once the stem is removed, check the color underneath. A green color under the stem indicates that the avocado is ripe and ready to eat.
If you find brown under the stem, the avocado is likely overripe. While it might still be edible, it could have brown, mushy spots inside.
Feel the Firmness:
After checking the stem, gently press the skin of the avocado with your thumb. A ripe avocado will yield slightly under pressure but shouldn’t feel overly soft. An avocado that feels hard will need a few more days to ripen.
Additional Tips:

If you buy an unripe avocado but need to speed up its ripening, place it in a paper bag with an apple or banana. The ethylene gas released by these fruits will help accelerate the ripening process.
Keep ripe avocados in the refrigerator to slow down further ripening, allowing you to enjoy them at their best for longer.
Conclusion: Choosing a ripe avocado doesn’t have to be tricky. By using the simple stem test, you can confidently select avocados that are just the right level of ripeness. This easy technique eliminates the guesswork and ensures you get to enjoy the delicious, creamy texture of avocados exactly as you like them.
