Peeled potatoes, raw. Thinly sliced. Do not rinse or soak.
cold butter, small cubes.
seasoning... salt, pepper... whatever you want, really.
Some fresh herbs, finely chopped... I like thyme, personally.
some heavy cream.
I also like to use a little blue-veined cheese.
Grease some parchment paper with butter, place it, butter up in your pan.
Lay a layer of potatoes down, all nice and flat-like. Season, dot with butter, dot with cheese.
a couple more layers of potato
more seasoning, butter, cheese... continue until all used up.
Pour cream over top of potatoes, let it "sink in".
Cover with more parchment and some weight... I use a pan (same size as the pan I am baking in) with a cast iron pan in that.
Bake at 350 for about an hour to an hour and a half.
turn out onto a cutting board and portion.
No curdling, no breaking.. and the end result is a beautiful golden crust and a tender, flavourful end product.
