So what's that meant to mean?
A Faux Fonds consists of layers of spruce placed under (and sometimes also on top) of a Reblochon cheese to act as a humidity regulator.
Indeed the "sandwich" is a sort of "belt and braces" activity or more likely a sign that the cheese was a shade too wet and soft when it was packed. The thin layer of woody matter is there to draw off the excess humidity of the cheese and also to put some back whenever it becomes too dry.
It's in fact an obligatory process for an PDO Reblochon. An important feature in cheese conservation...
And the title is not a particularly good translation of the French. Any suggestions from all you out there – with an F of course ? (But keep it clean!)
