Pumpkin and sage gratin

“Christmas is the one time we're encouraged to overindulge, and what a joy it can be”, says Anna Tobias, chef at London restaurant Café Deco. This recipe functions well as a side dish for her roast duck recipe – perfect for an intimate family Christmas. “The contrast between the sweet pumpkin, bitter radicchio, earthy sausage and salty parmesan is moreish. You can make this dish in advance and only do the final stage of browning the top when you want to serve it.”
