Wash as many plums, cut in half and stone them, pat dry and place in the buttered gratin / casserole dish like a roof tile as fit in the dish. That can be 950 g or 1050 g.
Beat the eggs until frothy, add the cream, vanilla pulp and the chopped goat cheese with a pinch of salt and carefully fold into the foam mixture.
Pour this mixture evenly over the plums in the mold (make sure that the cheese is evenly distributed) and bake at 180 ° in a preheated oven for 20 minutes with lower heat and then bake at 200 ° with lower and upper heat for 5 - 10 minutes until the surface gets color.
This gratin can be eaten hot, as is usual for a gratin, but I actually prefer it cold because the goat cheese then tastes better and the other flavors also harmonize better and you don`t burn your mouth on the plums!
