Is buffalo mozzarella the cheese they eat in spaghetti westerns? :D
If you mix a soup spoon of balsamico vinegar, a half of cup of boiling hot water, 2 spoons of olive oil and put in 1 bay leaf, half a handful of juniper berries, black and red pepper, salt and a little bit of grinded nutmeg, and of course, put the búfala mozzarella. And let it rest cooled for a few days in the refrigerator, you'll be in paradise!
2.59 Euro per 130g, or 4 euro per 100g - depends where you buy. The mozzarella made of cow milk is around per 80g 1.30 euro.
But the taste is worth it :)
