For this recipe, it is preferable to choose firm-fleshed potatoes.
Peel them (those who don't have a peeler yet, it's a must in the kitchen!)
Put the peeled potatoes in a bowl of fresh water as you go.
There are two choices for grating potatoes. The robot or the mandolin! I choose the second option.
You need a mandolin with a fine comb and a fairly thin layer. Darphin apples can also be made with a cheese grater with large holes.
Grate the potatoes.
For the Pommes Darphin, I choose the option chosen by the Auberge de Dully near Lausanne in Switzerland. During my culinary trip (see the report HERE!) I asked the cooks of this inn for their secret. And it was duck fat.
Put a good tablespoon of fat in a small pan or two in a large one. Let it melt.
Then add the potatoes. A certain thickness is required for the cake to be cohesive.
Cook over moderate heat for 10 minutes with a lid. Squeeze the potatoes with a spoon so that the juice comes out a little and gives cohesion. Turn the Darphin apples over like a pancake.
Let it cook again on the other side, this time without the lid, until the whole cake is golden brown!
Serve hot with a roast chicken just out of the oven (for example!).
