Potato and celeriac gratin
This dish makes a great side to a winter feast such as a roast lunch or dinner; the combination of potato and sour cream is hard to beat! When layering the potato mixture into the baking dish, keep the vegetable slices flat to avoid air pockets in your gratin.

Have your say
425ml thickened cream
140ml sour cream
85ml whole milk
2 cloves garlic, very finely sliced
2 sprigs thyme, leaves picked
100g chestnuts, peeled and cooked
salt and pepper
Preheat the oven to 180C.
Peel the potatoes and celeriac and slice very finely - a mandolin is best.
In a large saucepan, mix the creams and milk and bring to just under the boil. Add the sliced vegetables, garlic and thyme and cook gently for 5 minutes.
Slice the chestnuts. Season the vegetables well then layer half into an oval buttered gratin dish, about 33-centimetres long, spreading them evenly.
Spoon the chestnuts on top then layer over the remaining vegetables.
Bake for about 30 minutes or until golden and a skewer can be pushed through easily.
Cool slightly before serving with the lamb (see link below).
Serve with Frank's lamb shoulder with pomegranate glaze.
