an adaptation in the MMGG suggests pre-sterilizing both the verm and rice flour beforehand. Spread them out on seperate trays and bake at 300F for 20 minutes. Be careful that you dont overdo it. If you leave the rice flour in too long it will turn a darker brown and start to cook, losing nutrients.Keep in mind that you still have to sterilize again after you put your substrate in the jars.
