TRANSCRIPT
You probably notice when you cut an avocado in half that it starts to brown pretty quickly. There are a lot of methods out there but what I found really helps to slow down the process is the onion. Now what you're going to do is you're going to take a red onion. You're going to cut it up in large chunks. Throw it in the base of either a deli container or any bowl and then you take the other half of the avocado and place it on top. Make sure that you keep the half that has the pit and then cover it with either plastic wrap or the container and then throw it in the refrigerator. I've tested my theory against several different methods: lemon juice, the chlorine in water, plastic wrap, and nothing at all, and I've actually found that the onion does indeed work the best.
