I know using fresh herbs to infuse oil can be dangerous as the oil might become a breeding ground for botulism. I was wondering, if I first rinse my herbs (or peppers for that matter) and then dry them for several weeks/months, would it be safe to make an infused oil with these dried herbs compared to fresh ones?
Per the University of Ohio Extension, yes, it does reduce the risk (emphasis added):
Still, reduce is not eliminate. The guidelines to not can or hold the oil for long term continue to apply.
