Here's a fun thing.

Some time ago I decided that I was sick of throwing away so many aerosol cans of cooking spray, there had to be a reusable solution.  Enter Misto.  It is a refillable oil sprayer.  No chemicals or propellants added just a little bit of elbow grease.  You put the top on and give it a good 10 pumps to fill the bottle with air and blamo, a mist of oil.  The choice of oil is up to you.  Right now I have Filippo Berilo olive oil in mine.  I buy it in bulk in the pretty yellow can that you see behind my misto.  I use this oil to bake and pretty much anywhere that I don't want to waste my good cold pressed extra virgin.
