Add your whole avocados, and completely submerge them with cold water.
Close the container or zip-lock bag and keep it in the fridge.
The avocado will last well for about 2 weeks.
Notes
Remove the small stem at the top of the avocado. If it comes off easily and you see green underneath, it's likely ripe. If it's brown or difficult to remove, the avocado may be overripe or starting to spoil.
Ripe avocados tend to feel heavier compared to unripe ones of the same size. Hold the avocado in your hand and gauge its weight to get an idea of its ripeness.
Avocados can quickly transition from ripe to overripe, so it's essential to keep an eye on them and use them promptly once they reach the desired ripeness.
