DIY Cooking Spray

I dread buying cooking spray because of the price and the nasty chemicals store varieties contain. Naturally I was relieved when I found this recipe online for DIY cooking spray for just a fraction of the cost. 

You'll need:
Misting spray bottle (you can find these at the dollar store or at Walmart)
Olive oil (you could also use canola oil)
Water

Mix one part olive oil with five parts water. Pour into the spray bottle and shake. Store this cooking spray in a cool, dark place. 

In addition to being cheaper and more natural, this cooking spray will not leave that nasty residue on pans that most cooking sprays do.
