Bring the milk, vanilla pulp, salt, lemon and orange zest and sugar to the boil and stir in the semolina. Simmer over low heat for about 3 minutes while stirring.
Pour into a cold bowl. Add gelatine until dripping wet and dissolve while stirring. Stir in the egg yolks and let cool. Whip the cream until stiff. Mix about a third into the semolina, fold in the rest loosely.
Fill into dessert glasses and refrigerate for at least 4 hours.
Wash the strawberries, drain them well, clean and cut into small pieces. Mix with sugar, Grand Marnier and lemon balm.
Just before serving, cover the semolina flambées with the strawberries
