I have two methods that I use constantly, gratin dauphinoise and
crushed potato gratin The crushed potato gratin freezes perfectly part cooked or can be prepared up to 48 hours in advance and cooked later. Complete the final browning before serving. As gratin dauphinois is such a special dish, I would never re heat it or freeze it.
Gratin Dauphinois:Tips for Success:Gratin dauphinois is not as easy to make as it appears, one reason being that is takes a good 2 - 2 1/2 hours in a normal oven to cook the slices of potato, to allow the potato to absorb the cream and for that characteristic glazed top, patched with brown, to appear. Always allow the maximum time to cook it as it can rest for anything up to 45 minutes before serving after browning (on a low shelf or simply covered with a cloth). There is nothing worse than uncooked potato.
If you simply must make this dish but do not have the requisite 2- 2 1/2 hours for baking, use a pottery dish that will fit in your microwave and after the initial assembly cover with cling film, microwave on high for 10 minutes and then on low for 20, transferring to the oven to complete browning - about 20- 30 minutes. It will be very good, but not perfection.
There is no need to peel the potatoes, unless you wish to.
Slice the potatoes as thinly as possible; a mandolin works well, but frankly it is such a fiddle to use I simply do it by hand.
Save the 'ends' for soup as one of the keys to a truly great one is to arrange the slices tightly in concentric rings in the dish; their rounded shapes gets in the way.
After each layer sprinkle with a little salt and pepper and pour over a little of the cream/milk mixture. Continue until the dish is full.
This is a rich dish; don't skimp or it will just be dull and dry.
Season the cream mixture too; potatoes take quite a lot of salt
Rub a clove of garlic around the dish to scent with an aroma of garlic, but throw the garlic away.
Grate a little nutmeg over the top before it goes into the oven and dot with a little butter (30 g or so for 6).
I find the best results come from a cast iron enamelled baking dish; this transmits heat better than pottery.
Some recipes call for grated
Gruyère cheese, delicious but difficult to match the cheesy flavour of the dish with your chosen main course, so I prefer to leave it out. Others add egg yolks, fine but not necessary as it is rich enough already.
Ingredients:2-3 potatoes per person
Enough single cream, adding salt and pepper, to half fill the dish (this is one of the few occasions where I do not use
crème fraîche in a savoury dish; the sweet flavour of un-fermented single cream works better with the potatoes)
30 g butter (for six; scale up or down accordingly)
1 clove garlic
Salt pepper, nutmeg.
Method:Follow the instructions above; cover with foil and place on a baking dish in an oven at 160 degrees for 2 hours, then dot with the butter removing the foil and raising heat to 180 degrees for a final 15 minutes to brown the potatoes. Poke them with a sharp knife right in the centre of the dish, the potatoes should be tender and the cream absorbed. If they are not cooked properly then cook for another half an hour, covering with foil if the the popatoes brown too much.
Let the dish settle for 10 minutes on a surface of the kitchen, covered with a clean cloth, before serving. It will be much easier to serve nicely slightly cooler rtaher than piping hot.
(
Optional addition for gratin lyonnaise. For 6 people thinly slice 2 large onions and arrange them in layers in amongst the potatoes - nice with pork. Omitt the garlic.).
Poor man's potatotes is a dish from Spain, which is really a variation on gratin dauphinois. Melt 2 large onions, 2 cloves of chopped garlic, 1 tsp thyme and 1 jar of bottled red peppers in strips in 6 tbsp olive oil, until very soft. When they are cooked add them in layers to the above gratin recipe, using chicken stock or water and vegetable stock powder in place of the crème fraîche and milk. Proceed as above. This goes well with almost any well flavoured dish.
Crushed Potato Gratin:
This is very much easier to make than gratin daupinoise; almost fool proof in fact.
For 6 people, cut up about 750 g potato (peel if you wish, weigh the peeled amount then) and cook with 300 ml milk in a pan, with 1 tsp salt, nutmeg and pepper. When the potatoes are very soft crush lightly with a potato masher, add 150 ml crème fraîche and 30g butter, tip into a gratin dish, dot with a further 30 g butter and sprinkle with breadcrumbs. (At this point the potato mixture will look a little sloppy; never fear the liquid will be absorbed into the potatoes as they sit and cook more) Bake at 180 degrees for 30 minutes. (Optional addition - for garlic potato gratin, add 3 whole garlic cloves to the initial potato cooking pan.)
(Crushed potato gratin freezes perfectly; reheat for half an hour in a 160 degree oven. Can be made 24 hours in advance; reheat for the same length of time)Labels: Gratin Dauphinoise, potato gratin
