Avocado Is Our Star
How to keep avocados fresh
How do I keep Guacamole from turning brown?
Even the freshest guacamole won't stay that delicious, emerald shade for long once you've left it out and unprotected. Here are our tips to keep guacamole from turning brown:
Pat the guacamole down to give it a flat surface.
Pour a thin but visible layer of water or lemon /lime juice over the guacamole to form a barrier with the air.
Cover the dish with plastic wrap, pushing the wrap, so it is flush with the guacamole to prevent air pockets or put the guacamole in a sealed tub.
Put it in the fridge.
Remove the liquid, tasting your guacamole to be sure it is still fresh, then enjoy!
WHY DOES GUACAMOLE TURN BROWN?
Avocado flesh is green, but it darkens and eventually turns brown only when it reacts to oxygen in the air. The process of oxidation is kept at bay when the avocado is surrounded by skin, but once you cut and peel your fresh avocado, the flesh will begin to oxidize. This isn't noticeable for several hours, but beyond that, you will notice the flesh of your avocado changing color. Because avocado is the primary ingredient in guacamole, your guacamole will also turn brown as the avocado in it begins to oxidize.
HOW LONG WILL GUACAMOLE STAY GREEN?
For fresh guacamole, if well-sealed from the air, it should stay green for 1-2 days.
