Google is a good place to start... And actually, pickles are really simple: you need a basic brine - usually spices, vinegar, water and sugar. Ratios and blends depend on your taste. Here are links to my pickle and jam recipes. They will give you a sense of what you could do. I have also put chillies into a vinaigrette and bottled that. Also, you may want to grade / separate the hotter fnckers from the less hot ... That might be too much work.

I haven't got round to making some of these recipes downloadable, but I do have them in Word if you want them.

Oh and scrub them fingernails when your'd done.

Let me know how you go!

Leaving you with pictures in your head of showering upside down ;)
