Molly Stevens' Braised Celery recipe - take a dish of celery segments topped with a dose of sauteed aromatics (celery hearts, shallots, and thyme), and a bit of broth. Slowly cook it all down under a roof of tinfoil until it is nice, moist, and tender - then finish it off gratin-style with crunchy bread crumbs and a bit of nutty gruyere.
