Here is a weird one that blew my tiny mind. Submerge the cut side down of your avocado half in a shallow dish of water. Just a few millimeters deep. The water creates a perfect anaerobic seal—no oxygen, no browning.
It works brilliantly for half an avocado you plan to eat within 24 hours. Just dry it thoroughly before eating, or you’ll get a mouthful of sad, watery avocado soup.
Do not submerge the whole thing unless you want an aquatic avocado horror story. The skin will get mushy, and nobody has time for that.
