Viper's thread about death dust reminded me of the pickles my friend and I doctored.
We took a big jar (whatever size the bulk jar is) of Mount Olive pickles, minced a ghost pepper, and slice three jalapenos, and just added that to the pickles.
It's quite the treat for people who like spicy food.
Very, very simple, but after two weeks, it's really spicy.
We are now three months removed from the experiment, and most people can't eat these things without a big glass of milk or hunk of bread.
