Gratin de blettesSwiss chard gratin
Gratin de blettes is a thrifty winter favourite in Lyon and across Provence, where Swiss chard is a staple of every market garden and both the white ribs and the green leaves are used. The stalks are boiled until tender, the leaves wilted, and everything is folded into a nutmeg béchamel and baked under crisp breadcrumbs. It is served as a side with roasts or on its own for supper. The common mistake is not cooking the stalks long enough, which leaves them stringy. Chef's tip: peel the strings off the backs of the wide stalks like celery; the gratin will be silky.
