How many times have you bought or made something great, but not sure how long it will last or how/if it will save for the next day?  I found this website called stilltasty.com that helps you answer all of those questions and more.  I have used it to see how long certain veggies last, how to store and keep homemade lasagna and even homemade cookies/cakes.  They also have an app now, that you pay for, but its very helpful.  You can enter items in and it will remind you when they expire.
