Unfortunately, my chilli crop did not produce much this year but I always have frozen chillis in my freezer as it is the best way to keep them. They also chop really easily from frozen which is an added bonus.i even keep a few home grown chillies frozen whole to use for things like this.
I have a section of the freezer fro chillis, fresh (frozen?) ginger, galangal and lemon grass.
I am a bit of a spice fiend - not necessarily hot but often spicy (think cardamon or cinnamon or cumin or coriander or fenugreek or ... as well as chilli) - so have a full cupboard of seeds and grounds as well as the frozen options.
