Eating mold can be a tricky thing. There is a fine blue line between a perfectly ripe cheese and one that has gone on to wilder pastures. Cheese is a living food--not the kind with a heartbeat but one that ages and changes and goes through a life cycle. I tasted the cheese I'm writing about today, Fourme d'Ambert au lait cru, twice. Not different pieces either but the same chunk. Each time was at a different stage of the cheese's life and a vastly different experience.

The name is a little pretentious if you don't know French. "Fourme" comes from the Latin word for "form", a in which the cow's milk curds were held or pressed. The Italian word for cheese itself, "formaggio", has the same origin. In some French dialects "fourme" simply means cheese. So Fourme d'Ambert is cheese that originated in the town of Ambert. "Au lait cru" means "from raw milk" or unpasteurized. It is a blue cheese, a moldy molded cheese of France.

Fourme' d'Ambert is often called French Stilton. The grayish-green veins of blue mold run thick throughout. When I bought it, the cheese was cut to order (a good sign) and wrapped in cheese paper instead of plastic (a very good sign). When I opened it the next day after bringing the cheese to room temperature for an hour the texture was moist but still crumbled when cut. Spread on a cracker it was creamy and sweet yet pungent with the blue cheese flavor. Strong but not overpowering. It was a delicious cheese. My fiancée Fleming and I ate half of it then I wrapped it in plastic and returned it to the refrigerator.

Three days later I took the cheese and a few crackers with me to work for my lunch. By the time I unwrapped the cheese it had been at room temperature for a few hours. The smell, fungal and overpowering, almost knocked me out my chair. This was not the same cheese I had eaten days before. Undeterred by the pungency I cut of a chuck and spread it on a cracker. Even before it reached my mouth I could feel the fumes of something--mold maybe--entering my nose. The creaminess and sweet milk flavors were gone, consumed by the living cultures that had taken over. I ate the last of it but it left a bad taste in my nose and mouth.

Lesson: Cheese or any great food product must be taken care of properly and prepared and served at the peak of ripeness or freshness. Buying in bulk, even a bulk of two servings, may be fine for some ingredients, but not all and especially not some really great cheeses.
