I save Parm rinds and use them in soups and sometimes when cooking beans. I have to admit that I never stopped to taste the rinds but I’ve never picked up a moldy taste or smell in anything I've made with them. 
	 
	Edited to add that I’ve got some stashed in the freezer and will be sure to give them a good sniff before I use them.
