Don't get me wrong.
Tofu is amazing for our health, it's full of veggie proteins and whatnots, you can make it taste whatever you like and it has few calories. I love Tofu. Tofu is awesome.
But be warned. If said block of nutritious tofu is left forgotten at the back of the fridge for two weeks. It will turn a delicate shade of rosy-green speckled with light grey. Also, it will scent your entire fridge with a delightful aroma of pure *EVIL*!
I kid you not, if you need an easy solution to your evening chocolate cravings. Keep a rancid piece of tofu in your fridge and smell when needed. Foul!
