Who doesn't love avocados, right? Their creamy deliciousness goes great on toast, salads, and pasta.

Not to mention that guacamole wouldn't even exist without them.

And you might have heard that the best way to check if an avocado is ripe is by popping off that little nub at the top.

WELL STOP! It's actually a part of the stem, and it protects the avocado from the air.
When you pull the stem off, it exposes the flesh. This can cause the top of the avocado to ripen faster than the rest of the fruit.

Just like when you leave your guacamole out for too long, oxygen causes oxidation which turns it brown.
