Recently I spent time in the Marais, but not the lower part that most tourists visit, but in what is called the Haute Marais; the ever-growing hipper part of the Marais.
I stumbled upon a postage stamp size shop next to the famous Marche des Enfants Rouges Market that only sells the best, ham and Charcuterie from all over Europe. It's called Caractere de Cochon. I walked inside, took one look and one deep breathe and was hooked for like.
The owner, Solo, presides over this amazing shop and acting as a professor of the history and technique ham and sausage making and loves to teach clients, and it was here that I spent well over an hour enraptured by his conversation and my tasting of some of the best ham I have ever eaten. The hours are are hit and miss, so you'll need to have patience in trying to find an opening times ( as they vary all the time) , but OH! what wonders you'll see and taste.
