Eerie Food from Sardinia – Casu Marzu

Casu Marzu is eerie, very, very eerie. It’s a pungent cheese made from sheep milk and is left outside, uncovered, to rot. Tiny cheese flies infest the cheesy block and lay their off-spring, billions of small transparent maggots. The larvae feed on the cheese, thus causing fermentation and allowing the casu marzu to fully decompose into an eerie, stinky, creamy and highly sought after delicacy from the mountains of Sardinia. The moment I saw the sign above the door I knew what I had to do.

Hasu Martzu – Casu Marzu – Rotten Cheese at Mamoiada

In the six years that I’ve lived in Sardinia, I’d only ever heard tales of Casu Marzu. I had never seen it – that is until I went to Mamoiada and found a house full of the pungent cheese. The line-up to get in was astonishing long and I had no patience to wait so I politely pushed my way to the front of the line.

I did bust out my Italian skills and asked each elder as I passed “Mi scusi. Io non voglio comprare il formaggio, vorrei fare una foto. Posso andare avanti a Lei?” They all looked at me and knew I wasn’t Italian, smiled and allowed the crazy-smiling-Canuck to go on. “Molto gentile Lei, grazie e buonagiornata.”

For many years casu marzu was on the European Union’s banned food list, and offenders faced heavy fines if caught producing the cheese. However, it was still available on the black market where it could sell triple the price of a regular wheel of pecorino cheese.

Today, the ban on producing casu marzu was bypassed, thanks to the researchers at the University of Sassari and a large group of farmers who developed a hygienic way to produce the cheese, and noted a way around the ban when they learned, if an item of food has been produced for more than 25 years, the food item is automatically declared a ‘traditional’ food and is exempt from the banned food list.

By the time I arrived at the casu marzu house it was finished. I didn’t see any jumping maggots but the smell inside those walls was sharp, peppery and eerie.

Have you tired casu marzu? Would you try it?

  2. I’d definitely have a taste Jenny. I doubt that I’d be too popular on the flight home if I decided to buy some though, seeing as I only travel with cabin baggage these days.

    My father would make this when we were growing up in Connecticut, disgusting! The look the smell! Ultimate gross, but he and his friends loved it! I have never had the courage to try it. When we visited my first cousins in Anela, I mentioned that without any insult please don’t offer this to me for I know they had it and the previous year offered it to my nephew who almost lost his stomach. My father use to say Americans would be so much healthier if they ate all of the protein that those little maggots provided! I will still pass! It is really quite interesting though! Have a great week!

  5. I remember when as a kid I used to eat “casu marzu” and loved it, but you put “Gorgonzola” (blue cheese) in front of me and I would gag. I guess to each his own. You should try it, it’s actually very tasty spread on “pane carasau” and with strong local red wine. Let me know how it works out ( I can picture your face right now, hahaha).

  6. Eating or lets say tasting casu marzu or hasu marzu (the h is pronounced making a noise from the back of your mouth a bit like the french do) is really putting your mettle to the test. It is a challenge between you and the line up of your ancestors back to cro-magnon and beyond against evolution. If you survive, it means that you will be privileged to pass on your DNA to the future generations. So you just have to grin and bear it, swallow it down with courage and a splash of Cannonou and you can be confident that you are going to be stronger (or get extinct).Our existence is a daily challenge and this one is just a shade closer to the survival category of challenges and not just a puny artificial charade that one may encounter on the office floor – this is the real thing 🙂 . It also happens to be a quaint confirmation that we have something in common with the Australian aborigines a.k.a. “The Aussies” judging by their ancestral call for lunch: “Grubs up!!”

    • Regarding the Cannonou (I forgot how to spell that), too true! I think with a bottle of that I could even find Hakarl palatable! It’s not good wine, but it’s certainly good for obliterating the taste of whatever you’re eating.

      The next time you’re in Sardinia, make sure you get the Bottarga (make sure it is Sardinian and grey mullet) and you’ll be happy. Amazing. Every trip to Sardenga requires Casu Marzu, Bottarga, some random HORRENDOUS resin based wine, and a perfect plate of Risotto al nero di Seppia (spelling?) Oh, and a long night at Mama Tiana’s in Arzachena.

      Sardinia is the most beautiful place in the world. If you’ve only seen mainland Italy, you really must visit Sicily and more importantly, Sardenga (Sardinia.)

      • Personally, I’ve run into a Corsican cheese that makes Casu Marzu look positively tame from a ‘maggot counting’ point of view; however, the wonder of Casu Marzu is that the, shall we say, ‘excretions’ of the maggots is what makes it special.

        BTW, in ‘Asterix and the Corsicans’ there’s an example of a Corsican cheese like I’m referring to. I don’t recall the name of it, but I had a little with some Sardinian made Mirto (a little differnet from Corsican.) THAT was scary cheese. Little larva crawling EVERYWHERE.

  7. I JUST saw an episode of Bizarre Foods with Andrew Zimmern and he was in Sardinia eating that cheese, lol! My dad LOVES that stuff…would you believe that when I went to visit family with my brother (over 15 years ago) he actually made us bring home a BACKPACK full of cheese…and that one was in it?! Do I need to tell you how bad “we” smelt?! lol!!!!!

      • I’m sorry, but EVERY Italian knows about casu marzu, and even I as an American child of parents stationed in Palau/Santa Stefano had not only hard about it but actually tried it (with an ungodly bad glass of wine that made Cannoneau tastes like Crytal Rose!)

        When I was last there in 2000, it was trivially easy to obtain. Simply ask someone at a restaurant if they know of any and they’ll point you towards a farm that will hook you up.

        It’s not nearly as bad as it sounds and if you ‘ve got some wine to go along with it, it can be an extraordinary (in the good way) experience.

  8. Ah, what a great story about the famous maggot cheese! I personally have never tried it and I don’t think I will … but … never say never!!
