Liver casserole (maksalaatikko in Finnish) is a great dish, one of my favorites (especially this brand). Besides tasting delicious, it conducts electricity quite well. Maybe it is true what they say about liver containing lots of iron...
Good conductivity is good news for us CW operators: Morse code can be sent using the liver casserole as a telegraph key. A keying cable with alligator clips and a metal fork is needed.
Find clean locations on the aluminium edge and the fork and connect the alligator clips. Then connect the cable to your CW transmitter or audio oscillator. Touch the food with the fork to make CW signals, like in this video clip (I was trying to send fast because I was hungry and eager to start eating my key):
