Beat 2 egg yolks with 1 tbsp sugar until pale and fluffy.
Soak 3 leaves white gelatin in cold water.
Slit 0.5 vanilla bean lengthwise.
Carefully bring 250 ml milk with 2 tbsp sugar, 1 pinch lemon zest, 1 pinch orange zest, 1 pinch grated ginger and the vanilla bean to a brief boil in a saucepan.
Stir in 40 g durum wheat or soft wheat semolina and cook over low heat for 3 - 5 minutes into a semolina pudding, stirring constantly.
Take off the heat and remove the vanilla bean.
Gradually stir the still-warm semolina pudding into the beaten egg yolks.
Squeeze the gelatin out very well and add it. Stir until the gelatin has completely dissolved.
Stir in 1 tsp rum and 1 tbsp orange liqueur and let cool to room temperature.
Beat 1 egg white with 1 pinch of salt and 1 tbsp sugar to stiff peaks.
Whip the 200 g heavy cream to soft peaks and gently combine with the beaten egg white.
Fold the mixture into the semolina pudding and fill into 4 small molds (approx. 120 ml).
Cover and refrigerate for at least 2 hours.
Pit 600 g yellow plums and cut them into even pieces.
Mix with 80 g sugar, the juice of 1 lemon, 1 cinnamon stick and 0.5 vanilla bean, put in a large baking dish and let steep for 30 minutes.
Preheat the oven to 180 °C (350 °F), conventional oven (top and bottom heat).
Cook the plums on the middle rack for 12 - 15 minutes until soft, stirring frequently.
Take the roasted plum compote out of the oven and let it cool until lukewarm. Remove the cinnamon and the vanilla bean.
Arrange the semolina flummery with the roasted plum compote and enjoy.
