"Red is the colour of a tomato but also the shade most associated with blood and death - coincidence?"

Yep, that belladonna family includes potatoes - and they're obviously evil, being white and all

Nobody who's picked more than a handful of tomatoes would even think of having anything to do with the vines - it's where most of the 'tomato' fragrance is, but prolonged contact isn't recommended. Not nice to handle. (Although if you put some cleaned vine in with cooked cold tomato sauce and leave them in the fridge together for a couple of hours, the sauce will become more 'tomatoey' and you can then remove the vine and reheat the sauce - it won't work if you just drop the vine into hot sauce though)
