Swede, Kale and Sweet Potato Gratin

olive oil
butter
1 onion, finely sliced
1 swede, peeled and cut into batons
500g sweet potato, peeled and cut into batons
½ bunch (about 200g) kale, washed, thoroughly dried and very finely chopped
200ml whipping cream
100ml milk
for grating nutmeg
1 bay leaf

Heat the oven to 180C/fan 160C/gas 4. Heat a little oil and a knob of butter and gently fry the onion until it is very tender but not coloured.Add the swede and sweet potato, turn them over in the onion mix and season really well. Add the kale and then tip the lot into a buttered baking dish about 1.5 litres in capacity. Bring the cream and milk to a simmer and pour it over the veg, grate over some nutmeg and add the bay leaf.

Bake for 45 minutes, or until the veg are tender and the top is browned. The timing will vary depending on how shallow your dish is.
