Keeping avocados/guacamole green, and storing other foods

[healthy11]

This has nothing to do with special education, but with the upcoming football Super Bowl, avocado consumption is skyrocketing: www.producenews.com/index.php/news-dep-menu/test-featured/12021-super-bowl-leading-surge-in-avocado-consumption

I thought it would be nice to pass along the following article about best ways to keep your avocados and guacamole green: www.yahoo.com/food/kitchen-mystery-solved-the-secret-to-keeping-avocados-74315458637.html

They ran a test using different methods (like lemon juice, plastic wrap, oil) but The Kitchn recommends Start putting your freshly made guacamole in a container with a tight-fitting lid then push the guacamole down into the container to get rid of any air pockets. Next, pour 1/2 inch of lukewarm water on top, seal the container, and pop it in the fridge. When you’re ready to eat the guacamole, pour out the water and stir the guacamole to incorporate any surface moisture. That’s it. Supposedly guacamole stays green for several days using this method. Enjoy!

For keeping sliced avocado portions fresh, the following article recommends coating them with a light amount of cooking spray, like Pam: www.popsugar.com/food/How-Stop-Avocado-From-Browning-8513133

That makes total sense. I had a job at a sandwich shop when I was a teen and we would pre-make some of our specialty sandwiches in the morning before the lunch rush. Any leftover cut avocados were submerged in water and would stay green even till the next day. I have also purchased the bulk guac from Costco and frozen half of it with great results.
