I've got a copy of Debra Amien-Boyes' book, "200 Easy Homemade Cheese Recipes", and in addition to mesophilic culture, several of her recipes also call for something called 'aroma mesophilic culture.' I'm not exactly sure what that is. I got into cheese making through Ricki Carroll's book, "Home Cheese Making", and have gotten my supplies from her site, cheesemaking.com. I don't see anything called 'aroma mesophilic culture' there and wonder if they're just using different terms for the same thing. Can anyone clear up this mystery for me?
