My lot don't like spicy food, so I am removing the seeds to cool the heat down a bit, and i am laying them out on a baking tray.
I preheated the oven to 130 degrees, and the chillies went in quite low down in the oven. I left them for around 3 hours, checking on them sporadically, until they were completely dry.
(I think I might have left them a little too long! Ooops!)
I then just popped them in a sandwich bag, and into my spice drawer to use later.
