We grew chillies for the first time this year which was fun and very useful to have lovely fresh chillies on tap through the summer months. In the end though we grew way more than we could use so I kept the surplus chillies in a bowl on the windowsill in the kitchen and let them dry out naturally. I harvested the last of them in early October so they've had a good 8 weeks drying out.
I cut the stalks off and blitzed them in my magimix to create chilli flakes - perfect for curries, soups, stir-fries, chill - anything that needs a bit of a kick.
Quick tip: do not inhale freshly ground chilli flakes, it feels like your nose and eyes are literally burning. Really really unpleasant. Anyway, that aside it was very quick and once they were suitably flaked I put them in a jar in the pantry. Simples.
