Guacamole

The Kitchn recently appears to have solved one of those very annoying kitchen issues - how to keep guacamole from turning grey. In The Best Way to Keep Guacamole Green, they reveal that:

"All you do is cover the guacamole with a thin layer of water. 

OK, you say, this sounds weird - maybe even gross. Water on the guacamole? But water is a perfect barrier against oxygen, and since guacamole is dense, a little liquid won't water it down. I pour in a small amount of water to cover the top of the guacamole and refrigerate it for up to three days. After I take it out and pour off the water, I stir up the guacamole and the texture is no different than when it was made. In fact, I like the taste of guac after it has sat in the fridge overnight; I find the cilantro and onion flavors are blended better."

You can visit the page to see photos and read the step-by-step instructions. We must admit we haven't tried the technique, but it makes sense and it would definitely be helpful to be able to make guacamole ahead of time. If any of our readers get a chance to test this, we'd appreciate hearing your results.
