Serves six to eight
1.2 kg potatoes (maris piper, desiree or saxon)
300ml whole milk
400ml double cream
Good grating fresh nutmeg
Salt & pepper
Pre-heat the oven to 180C/Gas Mark 4.
Peel the potatoes and slice very thinly. A mandolin is useful for this. Heat the cream and milk in a pan and add the potatoes, seasoning very well. Add a grating of nutmeg and a clove of garlic made into a paste or very finely chopped. Simmer very gently for about ten minutes. Meanwhile, rub butter around the base and sides of a gratin dish (about 9” square or equivalent).
Put the potatoes into the prepared dish, pouring over any remaining cream. Bake in the oven for about an hour or until cooked and golden.
Either serve immediately or allow to cool. Then stamp out rounds of potato with a pastry cutter or cut into squares. Put onto a baking tray to heat up when required or put into a freezer container and freeze to use at a later date.
Heat at 180C for about 20 minutes or longer from frozen (about half an hour or so).
