Fat.  Let’s not beat around the bush, shall we?  Fat’s probably the best place to begin a discussion of Chicken Rillettes with Preserved Lemon and Summer Savory.  Au debut, as the French say, in the beginning, rillettes meant one thing – pork.  Or rather, pork and fat.  Rillettes was pork that had been salted, cooked slowly in pork fat, shredded, then preserved in the same fat, and served at room temperature, usually spread on toast.  Rillettes* are now found all over France, and while pork is still popular, in the Southwest, the Midi-Pyrenees, extending down to the Spanish border, the technique is more often seen with duck or rabbit.  Today rillettes of salmon, tuna or other fatty fish, or even mushrooms are not uncommon on pricey menus.  It’s hard to argue with that–what doesn’t taste good when cooked slowly in fat and salt?
