Check the color: many avocados darken as they ripen, but color alone is not always reliable
Gently squeeze the avocado in your palm: it should yield slightly to pressure without feeling mushy
Press near the stem end: if it gives a little, it is likely ripe
Remove the stem cap: if it comes off easily and shows green underneath, the avocado is ripe
If the stem cap is hard to remove, the avocado is likely unripe
If the area under the stem is brown, the avocado is likely overripe
Feel for firmness: very hard avocados are unripe, very soft ones are overripe
Check for even texture: avoid avocados with deep dents or very soft spots
Compare with your intended use: slightly firmer avocados are better for slicing, softer ones for mashing
Let unripe avocados sit at room temperature until they soften slightly
