Wow, tell me that trick really works? I thought only lemon juice works.

It doesn’t. The guac turns brown because of an enzymatic reaction between polyphenol oxidase and oxygen. The only ways to prevent browning are either an air tight container or something the deactivates the enzyme (like lime juice).

Edit- autocorrect typo, lime juice

No it doesn't work, but many people like to believe it does. There's no sensible reason why it would ever work for mashed up avocado.

Yep. And then I also use sour cream that helps quite a bit. And then I used canned jalapeno juice as well. It usually lasts for about 3 to 5 days before it starts really getting the icky brown. Couple years ago is when I started adding the pits to it before it would last, maybe two days. after adding pits is when it started getting a lot better 🙂
