Soak the raspberries in a little water with sugar over low heat. Let it cool and mix. Strain to remove the seeds from the coulis. Lightly beat the egg whites with a little salt and pepper. Prepare 3 plates: one with flour, the second with the beaten egg whites, and the third with breadcrumbs. Cut the cheese into small triangles, roll in flour, egg whites, and finally breadcrumbs. Fry the brie triangles for 3 minutes in oil at 350°F and serve on the raspberry coulis.
