Gently squeeze the avocado; it should yield slightly to pressure without feeling mushy
Check the skin color; many varieties darken as they ripen
Remove the stem cap; if it comes off easily and shows green underneath, it is ripe
If the area under the stem is brown, it is overripe
If the avocado feels very firm, it is not ripe yet
If it feels very soft or has sunken spots, it is likely overripe
Look for a slight give near the top and bottom when pressed gently
Use it within a day or two once it reaches ripeness
