Re: Chili powder versus Red Pepper Powder or flakes

Hai everyone… from my experience of making kimchi, I think I should use dried chili pepper and blend it until it become coarse/flakes. before this, I boil the dried chili pepper and then blend it with a little water, but my porridge become a litle watery… so, next time I think I have to just blend the dried chilli pepper instead of boil it and blend it with water. but I wonder, what proses I should use to make sure that dried chilli pepper is clean/hygiene. do anyone here have a good answer? (sorry for the bad grammar….hehehe)
