For the apricot casserole, briefly put the apricots in boiling water, rinse in cold water and peel off the skin, remove the seeds, cut into small pieces and stew in a little wine until soft, puree with a hand blender.
Cream the sugar and yolks, add the apricot puree (should be thick) and the flour, then fold in the beaten egg white. Pour the mixture into a buttered baking dish and bake at medium heat for about 30 minutes.
Then turn out of the mold and sprinkle well with sugar.
