Right now, I'm going to bust open a few food myths. I got these "true food facts" from the Food Network's very own super-chef, Alton Brown:

  • The first myth is that storing coffee in the freezer keeps it fresh. The reality is, taking the bag of beans out of the freezer every day causes temperature changes. And that causes water to condense inside the bag, which quickly degrades the flavor of the beans. So, store your beans in a cool, dry cupboard, instead.
  • You've probably also heard that putting oil in pasta water prevents the noodles from sticking together. Wrong, according to our master-chef. Noodles stick together because of the starch released when they cook. So, dilute the starch by boiling your pasta in lots of water. And don't waste the oil. Remember, oil floats on water   so it hardly interacts with the pasta at all.
  • And the final food myth is: You can prevent guacamole from turning brown by leaving the avocado pit in the bowl. The truth is, enzymes in avocado oxidize   or discolor   when they're exposed to oxygen. So, leaving the pit in your guacamole only keeps the part right under the pit from turning brown.    

The best way to keep your guacamole green is to mix in a tablespoon of lemon juice for each avocado you use.
