The best and only thing I ever cooked was...COW TONGUE!!!
To make this, you will first need to acquire a large cow tongue. Most butcher shops that process their own animals have these. They are usually frozen and out of sight (obviously), so you may have to ask at the counter.
When you get home, let it thaw. When it is fully thawed out, wash it thoroughly - just in case the butcher missed a spot - and maybe play with it a bit. Seriously, how often can you chase a sibling or spouse around the house with a giant animal tongue?
Ok, then you need a large pot filled with enough water to completely submerge the tongue. Boil the tongue with your desired vegetables (just like a regular roast beef) until it is tender and the skin peels off easily, usually around 1.5 to 3 hours.
Finally, slice it into managable chucks and enjoy!
NOTE: Do
NOT underboil your tongue. You will be in for a nasty shock when you eat it. It may still taste good, but it will be incredibly chewy and feel like...well, raw tongue. Also, don't tell you friends what it is until after they eat it.
