Cut Avocados: If you've only used a portion of an avocado and have leftovers, store the remaining portion with the pit still intact. Wrap it tightly in plastic wrap or place it in an airtight container.
Freezing Avocados: You can also freeze avocados if you have too many ripe ones or want to preserve them for later use. Mash the avocado flesh and mix it with lemon or lime juice to prevent browning.
