Today's tip is one of those that might be one you already know, but it is worth mentioning in case someone didn't.
Canned foods, especially those that are not able to be just poured out of the can, can sometimes stick. Some people pound on the bottom of the can to get the item to fall out, others will take a knife or spatula and help it out.
There is another way, and it's ridiculously easy.
Since I was going to use up some tomato paste, I figured I'd give an example!
Open up your can, then turn upside down and puncture two little holes in the bottom side of the can (using the can opener). This allows the pressure seal to release the contents, and voila! Can is empty!
