Preheat the oven to 180C/gas mark 4
Place the thinly sliced potatoes in a bowl of cold water, this will prevent them from browning, then rinse the slices and pat dry with kitchen paper
Add the cream or crème fraîche, milk (semi-skimmed or skimmed for a lower calorie meal) and the crushed garlic into a large saucepan. Bring to a gentle simmer and add the potato slices, cover the saucepan and then simmer for 10 minutes or until just tender. Season well.
Empty the contents of the saucepan to a greased ovenproof dish; sprinkle the cheese over the top. Pop in the oven for 25 minutes or until golden…take out and enjoy with good friends!
