Okay so it’s been brought to my attention that some of you are nervous to try blue cheeses because you have a penicillin allergy. Penicillium Roqueforti is indeed the blue mold that gives blue cheese its signature look and taste.
And as much as I adore blue cheese, I know it is not fun to break out in hives. The week before my 600 person wedding, I broke out into hives all over my face. ALL over. Imagine having what looked like the pimples of a 12-year-old all over your face, and welts all over your body like someone beat the crap out of you. The week before your wedding.
I spent an ungodly amount of money trying to figure out what I was allergic to. Turns out, I was allergic to planning a 600 person wedding. The Thursday before the week of the wedding, I still had table assignments to do, the hotel had a “snafu” with my bridal suite (like there was none), and I had an emergency root canal. Point being, my brothers and sisters in hives, this is not a pretty situation.
So I am by no means a doctor, but I have done some research on this. It appears that the consensus is that an allergic reaction to this cheese is not likely. When penicillium is consumed in this way, it is less caustic for some reason. However, always err on the side of caution if you feel funny about it.
