"Exactly as the title says, these are cooked in a muffin or Yorkshire pudding tin! They are a brilliant way to use up leftover potatoes & are so good that it's worth baking or boiling up some potatoes specially!! I use these all the time in our Chambres d'Hotes - it's easy to work out the portions and they freeze beautifully. There is also NO burnt mess in your gratin dishes! That's not to say I never make traditional Gratin Dauphinoise, because I do - but these are a great standby, use up leftover potatoes and look very elegant when served!"
You will need a deep 12 hole Muffin tin or 2 X 4 hole Yorkshire pudding tins.
Preheat the oven to 200C, 400F or Gas Mark 6.
Using 1 ounce of the butter, grease the muffin or Yorkshire pudding tins well. You can line the base with greaseproof baking paper for ease of removal if you wish.
Arrange the potatoes in the tin/s holes in layers - seasoning every other layer or so with the crushed garlic, salt & pepper.
Carry on until all the potatoes are used up.
Stir the creme fraiche with a wooden spoon to thin it down a bit - and then place a spoon on top of each mini potato gratin.
Sprinkle some grated cheese on top and then top each gratin with flecks of the remaining butter.
Grate some nutmeg on top and bake in the oven for about 30 to 45 minutes; it depends on which tin you are using - a muffin tin will take less time to bake than a Yorkshire Pudding tin as the holes are smaller!
