But I’m all for ways to get back to the traditional ways of making cheese, and this ‘recipe’ involves growing your own blue mold spores, similar to how it would have been done traditionally, rather than using a mass produced culture. Nonetheless, it is preferable from a food safety perspective to use P. roqueforti strains that do not produce secondary metabolites or mycotoxins as starter cultures in cheese manufacturing. The curd for Blue cheese is subsequently pierced to allow limited entry of O2 to promote growth of P. roqueforti. O'Connor, in Cheese Problems Solved, 2007. $26.99.
