Full credit for all the information and advice goes to this post; all I did was take the information and rearrange it into question and answer form.
How should I store Avocados? How long do they last?
First, keep avocados in a dry area.
How long they last depends on where and how you store them
If storing in the pantry:
- Avocados will become fully ripe in about four to seven days at normal room temperature
If storing in the refrigerator:
- Do not refrigerate avocados until they are fully ripe = allowing to ripen at room temperature will result in more flavorful avocados
- To extend the shelf life of fully ripe avocados, place them in a plastic bag and refrigerate. For best results, bring the avocados back to room temperature before using.
If storing in the freezer:
- You can freeze avocados. First, peel and puree them. Second, add .5 tablespoon of lemon juice for every avocado used to prevent browning. Third, place in a covered airtight container or a heavy-duty freezer bag.
- Properly stored, they will maintain best quality for 3-6 months, but will remain safe and edible beyond that time
How do I make Avocados ripen faster?
Put them in a brown paper bag, close it and leave it on the counter. To ripen them even faster, add an apple to the bag.
How do I tell if Avocados have gone bad?
The best way is to smell them. If they have an off odor, flavor or appearance, that is also a good reason to discard them.
