Here's a tip that shouldn't work:
When you get tuna juice on your fingers after opening the can, grab a spoon out of your cutlery drawer (I'm saying spoon but any stainless steel thing in the drawer will work). Run the cold water from the tap, and stick your fishy fingers holding the spoon vertically under the stream for a few seconds. I usually do it until my fingers are freezing... about 30 seconds. Dry your fingers and sniff. No tuna. So weird.
There's your handy dandy kitchen tip for today. These are few and far between, Peeps, so you better enjoy it. Do you have any to share with me?
