The suspect: a French cheese purchased at Bi-Rite Market.
Last seen: at a dinner party, where the hostess couldn't recall the cheese's name.
Distinguishing characteristics: a cheddarlike flavor and large salt crystals on the rind.
chocolatetartguy tried the cheese and wants to track it down, so he put out an all-points bulletin to the board: What could it be? grayelf suggests Mimolette, an orange Edam-like cheese with a pocked gray crust, which is the work of cheese mites that burrow into the milky surface and leave a cratered moonlike exterior after they've departed this mortal coil. If you're not easily put off by the idea of bugs snacking on your cheese, check out this 100-times-magnification video of a mite going to town on Mimolette.
The OP says that Mimolette is not the cheese in question; the one he tried was sharper and white, with definite salt crystals in the rind and the cheese, and a creamy, slightly crumbly texture.
