Potato Gratin

I haven’t made this since last winter, so the urge to do it confirms that we are inching inexorably closer to cooler temperatures. Yay to that.I always feel as though potatoes need help. On their own they’re a bit boring unless they’ve been turned into a chip or roasted in duck fat (but see – that’s helping too). Boiled, baked … blah. Salad? Only if they’re supporting something interesting. Mash?
