Winter Collection: Soft Roast Potatoes

I like my potatoes roasted this way, they get a nice sticky bottom and some crunch on the top. They're best made with my current obsession, Bartlett rooster potatoes but desirees will do.
Enough for 6
small knob of butter
2 tbsp olive oil
2.5kg rooster potatoes, peeled and cubed
200ml hot chicken or vegetable stock
grated rind and juice of 1 lemon
2 garlic bulbs
1 tbsp dried oregano

1 Preheat the oven to 180ºC, gas mark 4. Heat the butter and oil in a large roasting tin. Add the potatoes, stock and lemon juice and cook for 30 minutes, turning once or twice.

2 Separate the garlic cloves but do not peel. Add to the pan with the lemon rind and oregano and toss well together. Roast for a further 30 minutes, without turning until the potatoes are golden brown, the garlic is tender and the stock has disappeared
