What unique Kitchen/Cooking utensil is always in your TM

Not knowing where to start this but thought this cooking section would be a good place...

The one item I make sure is in the camping box is an old Hidden Valley Ranch dressing shaker.
There are many similar types out there for mixing powdered health drinks and such.
I use mine for every mixing task. You can scramble eggs with just a few shakes. Mix your favorite pancake batter, marinade, etc. Is great for instant pudding, mix and pour into cups. Just about anything you could do in a blender that does not require chopping up the ingredients. It seals shut so you can store what you don't use for later. Is easy to clean with a few shakes of soapy water and a rinse.
