How to Preserve
Store ripe avocados in the refrigerator to slow down the ripening process and extend their shelf life.
If you want to preserve a halved avocado, sprinkle the cut surface with lemon or lime juice to prevent browning, then tightly wrap it in plastic wrap or place it in an airtight container before refrigerating.
If you have a whole unripe avocado, leave it at room temperature until it ripens. Once ripe, you can transfer it to the refrigerator to maintain its freshness for a few more days.
