Here's what I do:

mix heavy cream, nutmeg, garlic, S+P, shredded gruyere. slice potatoes and bathe in the cream. transfer to baking dish. cover with rest of cream. baked at 350 covered in foil, poke several holes. when cream has reduced, cover potatoes with sliced gruyere and throw it under the broiler to brown.
