sweet potato gratin (serves 4-6)

Finally, a seriously simple but great gratin recipe.

1.5 kg sweet potatoes (or normal) washed and sliced into 5 mm slices

5 tsp sage, roughly choppped

6 garlic cloves, crushed with 2 tsp salt

1/2 tsp ground pepper

250 m double cream

Mix together everything but the cream. Arrange in a gratin dish by tightly packing handfuls of potato slices vertically (skin edges facing up) until dish is full. Cover with foil and bake in a 200'C oven for 45 minutes. Remove foil, pour over cream and bake a further 25 mins, or until potatoes are soft. Garnish with extra sage and serve.
