If I ever met Carrie McBride on the street, I would kiss her on the mouth. Who's Carrie McBride? Truth be told I'm not really sure. I know only thing about Carrie McBride, that one thing being enough to warrant a friendly and full-fledged makeout session on the streets of New York - she discovered this genius + guaranteed method for keeping guacamole green in the fridge.
Carrie's idea is so brilliant because it enables you to actually make guacamole the day before, storing the dip overnight (which I think actually makes it taste better) before a party without turning brown. I have also heard tales of people having something called 'leftover guacamole', to which this method could be also be applied.
So what's the secret? Place your guacamole in a container, leveling off the top as much as possible, and gently cover the guacamole with a thin layer of......water. Yep, that's it. Water. No pits, no limes, no saran wrap. Just plain old water. Put a lid on your container and store in the fridge.
The next day, simply pour out as much of the water as possible & then stir, folding in what little water you couldn't pour out.
I put this to the test, and it 100% works, the only hard part being not eating the guacamole so that there would be something to test. In fact, I woke up twice in the middle of the night thinking about the guacamole in the fridge. I have a problem.
